Friday/ at the airport ✈️

My time in Mazatlán was over on Friday morning 😢.
My stuffed axolotl from the Gran Acuario Mazatlán gift shop went into the suitcase with my clothes, and now I am at Mazatlán airport.
I will try to get a few airplane pictures before we board. 

Update at Sat 12.30 am:
I made it home.
That connection to Seattle for international arrivals into LAX is quite something.

We arrived at the gate at LAX at 5.55 pm.
The flight to Seattle was going to leave at 7.40 pm.
First, there is a very long walk through a labyrinth of walkways and hallways to get to the US Customs and Border Control point. I said to a friendly official that they need to put more signs up for us, to which she replied – oh, but you should ‘just look for open doors’ if you don’t know where to go next.

(The problem was that I had no crowd to follow. A group of people in front of me on the airplane took so long to disembark, that the rest had disappeared completely out of sight by the time I stepped off.
Where did everyone go? 😱)

Anyway, there was no Global Entry kiosk open at Customs and Border Control (they are part of the partial government shutdown that still has not been resolved). So instead, there was a facial recognition photo check for everyone, regardless if you had Global Entry credentials or not. The camera did not recognize everyone and those were then directed to an official for a manual passport check.

Now I still had to pick up my bag from the international arrivals carousel for rechecking it for the flight to Seattle. That took a very long time as well, after which you get ejected into the public area at Terminal 6.
So now you go up the escalator, to go through the standard domestic flight security check again— which ate up the remaining time I had for the connection.
My flight to Seattle was already into boarding Group E by the time I had gone to the restroom and taken a few bites out of a sandwich and banana that I had bought hastily.

There were puffy white clouds in the view of the Pacific Ocean by Olas Altas beach this morning.
From Wikipedia:
The axolotl (Ambystoma mexicanum) is a species of paedomorphic mole salamander. They mature into the terrestrial adult form without undergoing metamorphosis; the adults remain fully aquatic with obvious external gills. This trait, although somewhat unusual among the majority of amphibians, is not unique.
Axolotls originally inhabited a system of interconnected wetlands and lakes in the Mexican highlands. They were known to inhabit the smaller lakes of Xochimilco and Chalco, and are also presumed to have inhabited the larger lakes of Texcoco and Zumpango. These waterways were mostly drained by Spanish settlers after the conquest of the Aztec Empire, leading to the destruction of much of the axolotl’s natural habitat, which is now largely occupied by Mexico City. Despite this, they remained abundant enough to form part of the staple in the diet of native Mexica during the colonial era.
Today, due to continued urbanization in Mexico City, which causes water pollution in the remaining waterways, as well as the introduction of invasive species such as tilapia and carp, the axolotls are now near extinction. The species has been listed as critically endangered in the wild, with a decreasing population of around 50 to 1,000 adult individuals.
A large captive population of axolotls currently exists, though, with the specimens being used extensively in scientific research for their remarkable ability to regenerate parts of their body, including limbs, gills and parts of their eyes and brains.

Wednesday/ at the Gran Acuario Mazatlán 🐠

The Gran Acuario Mazatlán hosts over 250 species of fish. It is the is the largest aquarium in Latin America.

It contains a marine museum, the Gulf of Mexico Oceanic Fish Tank, a walk-through aviary, a boardwalk along the lagoon outside, crocodile exhibits, and a capybara petting area. The penguin area and flamingo area are currently closed. 

The new Gran Acuario Mazatlán opened to the public in May 2023.  This large new set of concrete structures and spaces were designed by architecture firm Tatiana Bilbao Estudio from Mexico City, and replaced the old municipal aquarium.

A beautiful pyramid sea star (Pharia pyramidata).
About 1,900 species of starfish form the taxonomic class Asteroidea. These creatures live on the seabed and are found in all the world’s oceans, from warm, tropical zones to frigid, polar regions. They can occur from the intertidal zone down to abyssal depths, at 6,000 m (20,000 ft) below the surface.

Tuesday/ the total lunar eclipse 🌑

Here are my amateur pictures of the early morning hours’ total lunar eclipse, taken with my Sony a7CR and Tamron lens at 5 times zoom (200 mm).

The next total lunar eclipse will be in 2028.

Here is Katrina Miller explaining in the New York Times why the moon is red during a total lunar eclipse:
A total lunar eclipse occurs when the entire moon slips into the umbra, during which most of the sunlight illuminating the lunar surface is blocked by Earth. But some sunlight spills over the edges of Earth and through its atmosphere, which more readily scatters blue light. That leaves red light, which has an easier time passing through the atmosphere, lighting up the face of the moon and causing it to shine scarlet.

Friday/ the whale museum & more 🐋

There was a marine layer out on the ocean this morning as we made our way to  Cerro del Vigía (‘Lookout Hill’).

We took the short cable car trip up to the observatory: the touristic park named Observatorio 1873, after the year of its construction.

By the observatory there is a small agaviario (a dedicated agave garden) and steps down to a bird sanctuary called El Nido.  A few steps further down the hill there is an enclosure with iguanas and tortoises.

The last stop is the new whale museum called Museo Nacional de la Ballena (National Whale Museum) that opened in August 2025. 

(Thanks to Bryan for the picture of the toucan and of the green parrot).

Tuesday/ the Snow Moon 🌕

I had a great view of the Snow Moon this morning, looking through my kitchen window.
The Snow Moon is the traditional name for the Full Moon in February, named for the heavy snow typical of this month in North America.

Looking out my kitchen window towards the west, at 7.15 am just before sunrise. Sunrise is at 7.32 am.

Thursday/ the year’s last supermoon 🌕

Tonight the last supermoon* of the year— and the third in a consecutive sequence— is out. (There will be a fourth supermoon in this same celestial series in January 2026).

We have cloud cover and lots of rain here in the city in Seattle tonight, so for now I can only look for pictures of the supermoon online.

*A supermoon is a full moon that occurs when the Moon is at or near its closest point to Earth in its elliptical orbit, a point called perigee. This proximity makes the Moon appear slightly brighter and larger than an average full moon, although the difference may be difficult to notice with the naked eye. The term can also technically apply to a new moon, but it is typically associated with the visible full moon.

Sunday/ Christmas lights 🎄

I took the No 10 bus to Westlake Center at sunset to check out the Christmas tree and its lights. (Pike Place Market is just a few blocks away).

There were not a lot of people around, probably because it was chilly (43°F/ 6°C). A few Seahawks fans were back from Lumen Field, where the Hawks took out the Minnesota Vikings 26-0 tonight.

Wednesday/ Viking I at 50 🛰

It’s been 50 years since the launch of Viking I, the first US spacecraft ever to land successfully on Mars.
Research from recent years suggests that the lander touched down where a Martian megatsunami deposited materials 3.4 billion years ago.

A model of Viking 1.
(The remains of the original Viking 1 lander are on the surface of Mars, where it had landed on July 20, 1976. It was a stationary lander and did not roam around. It did have an orbiter with solar panels that completed 1,485 orbits around Mars. While it no longer transmits data, the orbiter continues to orbit the planet! )
Construction of the Viking 1 spacecraft was done primarily by the private company Martin Marietta (now Lockheed Martin). The team worked for six years to build the ground-breaking spacecraft. The cost came to roughly $1 billion— about $6 billion in today’s dollars.

This timeline was compiled for MSN online by Dede Wilson:

1. The Historic Liftoff
The countdown ended in a roar of fire and smoke as Viking 1 lifted off from Cape Canaveral on August 20, 1975. The Titan IIIE-Centaur rocket carried both an orbiter and a lander, marking NASA’s boldest step toward exploring Mars.

2. The Long Cruise to Mars
Viking 1 traveled nearly 11 months through space before arriving at Mars. This interplanetary cruiseinvolved careful navigation to ensure the spacecraft reached its target orbit with pinpoint accuracy.

3. Mars Orbit Arrival
On June 19, 1976, Viking 1’s orbiter fired its engine to settle into orbit around Mars. From this vantage point, it began photographing the surface to find a safe and scientifically valuable landing site.

4. The First Soft Landing on Mars
On July 20, 1976, exactly seven years after Apollo 11’s Moon landing, Viking 1’s lander touched down in Chryse Planitia, becoming the first fully successful Mars lander in history.

5. Stunning Panoramas of a New World
Viking 1 sent back the first high-resolution panoramic photos of Mars, revealing a rocky, rust-colored landscape beneath a salmon-pink sky, images that captured the imagination of people worldwide.

6. Searching for Life
Equipped with biology experiments, Viking 1 attempted to detect signs of life in Martian soil. The results were puzzling: some tests gave unexpected positive readings, but most indicated no organics, sparking debates that continue to this day.

7. Mapping Mars from Above
The orbiter mapped vast swaths of the planet, from giant volcanoes like Olympus Mons to canyons deeper than Earth’s Grand Canyon. These images shaped our understanding of Martian geology.

8. Years of Operation
Viking 1’s lander operated for over six Earth years (2,245 Martian sols) making it the longest-running Mars surface mission until 2010, when NASA’s Opportunity rover broke the record.

9. A Sudden Goodbye
In November 1982, a faulty command ended communications with the lander. The orbiter had already completed its mission, but Viking 1’s contributions to science remained secure.

10. Inspiring Future Mars Missions
From Pathfinder to Perseverance, every Mars mission since Viking 1 has built on its legacy. It proved we could land safely, operate for years, and study Mars in depth.

Wednesday/ off Gough Island 🪨

Check out this cool 1979 envelope.
It was mailed paquebot off Gough Island, with all kinds of outrageous postmarks on the envelope.

Paquebot cancellations on postage stamps indicate that the mail was posted on a ship at sea and canceled at the ship’s next port of call.
The term paquebot is French for “packet boat” (steam ship, steam vessel) and signifies that the mail was handled according to international regulations for mail posted on vessels. These cancellations are distinct from regular postmarks and are often sought after by collectors. 

Postmarks and stamp on envelope—
S.A. Agulhas is a South African ice-strengthened training ship and former polar research vessel. She was built by Mitsubishi Heavy Industries in Shimonoseki, Japan, in 1978. S.A. Agulhas retired from Antarctic service in April 2012 when the replacement vessel, S. A. Agulhas II, was commissioned. She was transferred to the South African Maritime Safety Authority as a training ship.
Mailed paquebot off Gough Island on Nov. 2, 1979.
Penguin and Gough Island coordinates. Gough Island is home to northern rockhopper penguins (Eudyptes moseleyi).
Neutron research postmark from University of Potchefstroom in South Africa. The main scientific station on Gough Island is a South African weather station, which has been in operation since 1956. The Physics department at Potch University studied cosmic rays. Cosmic rays are primarily composed of high-energy particles, with about 90% being protons (hydrogen nuclei). Neutrons are secondary particles that are knocked out of atoms in the earth’s atmosphere.
The blue helicopter postmark is most likely a commemorative or mission-specific cachet used on mail handled during the 1979 Gough Island expedition. The 22 might refer to a flight number or a team identification.
The Cape Town postmark of Nov. 17, 1979 likely marks the arrival of the vessel there, at which time it was dispatched to the street address in Stellenbosch.
The 4c stamp is from South Africa’s Third Definitive Series
Issued May 27, 1977 |4c Protea longifolia |Perf. 12½ |Photogravure |Fluorescent paper |No watermark
Look at the bottom of this map for Gough Island.
The island is also known historically as Gonçalo Álvares, and is a rugged volcanic island (area 35 mi²) in the South Atlantic Ocean.
It is a dependency of the Tristan da Cunha island group and part of the British overseas territory of Saint Helena, Ascension and Tristan da Cunha.
Nobody lives on Gough Island except for the workers of a weather station, which is usually six people. The South African National Antarctic Programme has maintained the island with British permission since 1956.

One of these stamps would have fitted the envelope perfectly.
Unfortunately, it would be 18 more years after 1979 before these stamps featuring the Antarctic skua would be issued.

Tuesday/ the 8.8 earthquake 🌎

My phone and watch buzzed a dozen times from my Japan-based NHK app tonight, with tsunami warnings (because of the 8.8 earthquake on the Kamchatka peninsula).

By now the first waves have reached Hokkaido in the north of Japan, though, and it seems the waves will be no more than a few feet high.

Why was this the case? I asked Chat GPT’s AI chatbot.
Great question — and a very reasonable one, given how large-magnitude earthquakes like the 8.8 off the Kamchatka Peninsula can sometimes generate devastating tsunamis. But not all big earthquakes produce massive waves. Here’s why this particular one likely produced only a small tsunami (a few feet):
1. It was very deep
2. It was likely within the subducting slab
3. The tsunami threat is highly dependent on the type of fault motion
4. Energy was spread over a wide area

Magnitude: 8.8
Depth: 21 km 13 mi
Time: GMT 2025-07-29 23:24:50.842
Epicenter: 2025 Kamchatka Peninsula, Russia Earthquake
Agency: USGS (United States Geological Survey)

For this extremely strong earthquake, 64 aftershocks (above mag. 2) have been detected so far. The strongest was a magnitude 7.2 quake that hit 53 seconds after the mainshock in 81 km (50 mi) distance, in 94 km southeast of Vilyuchinsk, Yelizovsky District, Kamchatka, Russia, on Wednesday, Jul 30, 2025 on 11:25 am (Kamchatka local time GMT +12). The most recent aftershock occurred 5 hours ago 217 km south of Petropavlovsk-Kamchatskiy, Kamchatka, Russia, and had a magnitude of 4.9.

The majority of reports came from Petropavlovsk-Kamchatskiy (58 reports), a city with more than 180,000 inhabitants in Kamchatka in 119 km (74 mi) distance northwest of the epicenter, Russia, Yelizovo (10 reports), a town with 41,000 inhabitants in 140 km (87 mi) distance northwest of the epicenter, and Yakutsk (4 reports) (2,085 km or 1,295 mi to the northwest) in Sakha.

Thursday/ AI does hard math 🧮

Cade Metz reports from San Francisco for the New York Times:
An artificial intelligence system built by Google DeepMind, the tech giant’s primary artificial intelligence lab, has achieved “gold medal” status in the annual International Mathematical Olympiad, a premier math competition for high school students.

It was the first time a machine — which solved five of the six problems at the 2025 competition, held in Australia this month — reached that level of success, Google said in a blog post on Monday.

Google said Deep Think had spent the same amount of time with the I.M.O. as human participants did: 4½ hours. But the company declined to say how much money, processing power or electricity had been used to complete the test.


I looked up the problems online, and here they are.
Oof. Should I give it a go, and put in two sessions of 4½ hours each?
I think I’d better not. I might damage my self-esteem. 😆

Thursday/ ocelot & opossum 🐆


Researchers at Cocha Cashu Biological Station in southeastern Peru set up a camera trap to study bird behavior, but they got a surprise guest appearance instead: an ocelot trailing an opossum through the jungle at night.
The ocelot, a wild cat slightly larger than a house cat, and the common opossum, a marsupial, are usually predator and prey. But in this video, they moved in tandem— like two old friends walking home from a bar.
Intrigued, they contacted researchers in other parts of the Amazon who turned up three additional, nearly identical videos from different locations and years.

Opossums’ attraction to ocelots remains a mystery, but Dr. Damas-Moreira and her colleagues suspect there’s something that draws both animals. One hypothesis is “chemical camouflage.”
“Opossums have a strong smell, and a close-by ocelot might help hide the opossum’s scent from bigger predators, or the opossum’s odor might mask the ocelot’s presence from prey,” said Ettore Camerlenghi, an evolutionary biologist and ecologist at ETH Zurich and an author of the study.
Opossums are also resistant to the venom of pit vipers, a snake that lives in the Amazon. Ocelots lack that defense, and teaming up could give both animals an edge when hunting, Dr. Camerlenghi said. In North America, a similar alliance exists between coyotes and badgers, who buddy up to hunt squirrels.

Wednesday/ an interstellar comet ☄

There is an interstellar comet in our solar system, only the third known time it has happened.

Kenneth Chang writes for the New York Times:
For only the third time, astronomers have found something passing through our solar system that came from outside the solar system.

This interstellar object, known as 3I/ATLAS, is still pretty far from the sun, currently located between the orbits of the asteroid belt and Jupiter but heading toward the inner solar system.

“This thing is traveling pretty fast” said Paul Chodas, director of the Center for Near Earth Object Studies at NASA’s Jet Propulsion Laboratory in California.

Relative to the sun, it is currently moving at about 130,000 miles per hour and it will continue to accelerate as the sun’s gravity pulls on it.
The first known interstellar object was Oumuamua, which traveled through the solar system in 2017. In 2019, Borisov, a comet of interstellar origin, passed by.

A diagram shows the projected trajectory of the interstellar comet 3I/ATLAS, labeled C/2025 N1 here, as it travels through our solar system.
It is not yet known how big it is, but it will pass well clear of Earth. Its closest approach to Earth will occur in December, at a distance of 160 million miles.

Wednesday/ stamps from Ciskei 🦉

I have expanded my South African stamp collection to include the four Bantustans (homelands) that had issued postage stamps from 1976 to 1994. Technically these are not stamps from South Africa.
Although these stamps were denominated in South African Rand, they were not valid for mail that was sent from outside the homelands.

Below is a sampler of pages from my collection for Ciskei.

First, a little history. This is what South Africa looked like before the first democratic election of 1994. The four main provinces were established in 1910, and the Bantustans (homelands) were established by the South African apartheid government.
After the 1994 election, the Bantustans ceased to exist, and were reincorporated into South Africa.
Nine new provinces were established: Eastern Cape, Free State, Gauteng, KwaZulu-Natal, Limpopo, Mpumalanga, Northern Cape, North West, and Western Cape.

[More from Wikipedia: Bantustan]- 
A Bantustan (also known as a Bantu homeland, a black homeland, a black state or simply known as a homeland) was a territory that the National Party administration of the Union of South Africa (1910–1961) and later the Republic of South Africa (1961–1994) set aside for black inhabitants of South Africa and South West Africa (now Namibia), as a part of its policy of apartheid.
The government of South Africa declared that four of the South African Bantustans were independent—Transkei, Bophuthatswana, Venda, and Ciskei (the so-called “TBVC States”), but this declaration was never recognized by anti-apartheid forces in South Africa or by any international government. Other Bantustans (like KwaZulu, Lebowa, and QwaQwa) were assigned “autonomy” but never granted “independence”.

Tuesday/ time for ice cream🍦

A deadly, record-setting heat wave was continuing to blast most of the eastern U.S. on Tuesday, June 24, forecasters said, with temperatures soaring to near 100 degrees for tens of millions of people.
– USA Today


We’re still escaping the heat here in Seattle, with a relatively mild high of 79°F (26°C) here today.
Here is a mathematics-and-ice-cream cartoon from today’s Seattle Times, from cartoonist Bob Thaves.

Euclid is generally considered with Archimedes and Apollonius of Perga to be among the greatest mathematicians of antiquity.
Euclid’s book ‘The Elements’ was a comprehensive compilation and explanation of all the known mathematics of his time, and the earliest known discussion of geometry. The Elements is often considered after the Bible as the most frequently translated, published, and studied book in the history of the Western World.

Monday/ looking at the stars 🔭

The first images of the brand new Vera C. Rubin Observatory in Chile have come in.
The completion of the telescope’s construction has been two decades in the making. It was built on a mountain in northern Chile, in the foothills of the Andes, and on the edge of the Atacama Desert. The altitude and dry atmosphere around it provide clear skies for observing the cosmos.

From Kenneth Chang and Katrina Miller’s reporting in the New York Times:
Rubin is far from the largest telescope in the world, but it is a technological marvel. The main structure of the telescope, with a 28-foot-wide primary mirror, an 11-foot-wide secondary mirror and the world’s largest digital camera, floats on a thin layer of oil. Magnetic motors twirl the 300-ton structure around — at full speed, it could complete one full rotation in a little more than half a minute.
Its unique design means Rubin can gaze deep, wide and fast, allowing the telescope to quickly pan across the sky, taking some 1,000 photos per night.
By scanning the entire sky every three to four days for 10 years, it will discover millions of exploding stars, space rocks flying past and patches of warped space-time that produce distorted, fun-house views of distant galaxies.

Wednesday/ the strawberry moon 🍓

We had a little bit of June gloom this morning with cool weather and low clouds.
The clouds are mostly gone now, so maybe I will get a good look at Junes’s Strawberry Moon* tonight.

*Named thus not because of the reddish glow, but because strawberries are harvested in June.

Tuesday/ surface tension 💧

The weather was cool today (55°F / 13°C), with a light rain— just enough to form pearly droplets on plants with large, waxy leaves.

I believe these are redwood sorrel (Oxalis oregana) leaves.

It made me look up the surface tension* of water again (see table below). Water has the highest surface tension of almost all common liquids.
There is mercury of course, that blows all the competition away.
On the low end, liquid helium stands alone with virtually no surface tension, and in a state of superfluidity it flows without friction or viscosity.

*Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Surface tension is what allows objects with a higher density than water such as razor blades and insects to float on a water surface without becoming even partly submerged.

Friday/ a crescent moon that smiles 🌙

Happy Friday.
I got up early this morning and went outside to look for the crescent moon, Venus, and Saturn close together in the sky, but didn’t see anything.
They might have been too low on the horizon for me to see here from my house.

This is an image generated by Stellarium’s planetarium software for April 25, 2025, at 5:30 a.m. CDT, of the conjunction of the crescent moon, Venus and Saturn.
These three together, form what has been billed as a cosmic “smiley face.”
It takes a little imagination to see the smiley face, but OK— we’ll go with it.
I believe the red E at the bottom of the image stands for Earth.
