Total Solar eclipse of 12th August 2026 as seen from near Osorno, 50 km west of Burgos, Spain. This was a low eclipse, so the corona looked yellowish during the totality of 1 minute 45 seconds.

Now I have a minor planet. It was discovered by Ovidiu Vaduvescu using images by Euronear Project taken at Roque de los Muchachos, La Palma, Spain. This is a 2.2-km wide asteroid, revolving around the Sun every 5.62 years, at an average distance of 470 million km.🗿🙂

Picture of a text from IAU WGSBN bulletin, which read as follows: (819712) Tezel = 2014 LL32 Discovery: 2014-06-06 / EURONEAR / Roque de los Muchachos / 950 Tunç Tezel (b. 1977) is a Turkish civil engineer, eclipse chaser, astrophotographer, and member of the Turkish Astronomy Society. Well-known for pictures of skyscapes and long-term motions of planets including retrograde motions and analemmas, he is also the creator of Tutulemma, an analemma photograph that includes a solar eclipse.

Retrograde Neptune & Saturn 2025-6

vimeo.com/1177973763

I photographed Neptune and Saturn every 6 to 11 days between 9th May 2025 and 25th February 2026 while both planets traced their retrograde loops.
Neptune and Saturn trace their retrograde loops between 9th May 2025 and 25th February 2026. Saturn looks like a yellowish 1st magnitude star, tracing a loop of 7 degrees long, beginning in Pisces, then crossing to Aquarius at lower right just before October, and then making back to Pisces. Neptune's retrograde loop is more compact, visible as a series of 8th magnitude aqua-green dots spanning 3 degrees in Pisces. The separation between Saturn and Neptune changes along the course of the year, as the planets trace different retrograde loops according to their own orbital velocities around the Sun, and also their distance. This has been the closest Saturn and Neptune have been in the sky since their last conjunction in 1989.

@wilwheaton.net day today.🖖😎
The Big Bang Theory scene. It is a movie theatre, Kootrapali, Wolowitz, Leonard look at somewhere at the back as Wil Wheaton in a Star Trek TOG blue uniform says "Yeah?" and utters one of the best lines in movie business: "Live long and suck it!"

The appearance of Comet Hyakutake in 1996 had ended a long drought of great comets. But the weather in March 1996 was not very favourable. I was able to see Hyakutake at its closest for 10 minutes only. When I took this single picture 30 years ago today, clouds were coming back already.
Comet Hyakutake is visible with its long tail, not far from Alkaid and Mizar, two stars of Big Dipper in Ursa Major. Clouds shining in yellow-orange (because of the light pollution) are about to cover the comet in aqua-green colour.

I had photographed 21st February 2008 eclipse from Kaş, Turkey, whereas Petr Horalek shot the pictures of 3rd March 2026 eclipse from Kitt Peak, Arizona.

Souvenir shot of total Lunar eclipse of 3rd March 2026, around the beginning of totality.🌚 This is from Flamingo Campgrounds in Everglades NP, Florida.
The Moon in total eclipse on 3rd March 2026. Dark reds in upper left gradually go lighter towards lower right, which has bright red and orange tones; the full Moon looks like a peach.

Twilight With Moon and Planets

Saturn, Mercury, Venus and the Moon shine through bright twilight in the evening of 19th February 2026, as seen from Kirazlı village on the road between Bursa and Uludağ NP.
Saturn, Mercury, Venus and the Moon shine through bright twilight in the evening of 19th February 2026. Lake Uluabat can be seen in the distance, overflowing its basin, filled with rains and snows of this wet and plentiful winter. The immediate foreground of fields around Kirazlı village is white with fresh snow. Same as first picture, with Saturn, Mercury and Venus labeled.

Star Trek: Lower Decks scene. Upon the choice of Bradward Boimler in a FRP game designed by Ferengi, General Martok in the computer game screen delivers in Pic. 1: "The bartender rips your arm off and kills you with it." As Mariner, Rutherford, Boimler and Tendi watches, Martok continues in Pic. 2: "It is not an honorable death..." Mariner slightly turns to Boimler and smirks in Pic. 3, while Martok says:"...since technically you have died by your own hand." Alt in Pic. 1. Alt in Pic. 1 also.

2 Worlds, 2 Analemmas
apod.nasa.gov/apod/ap25062...

The Martian analemma was presented by @elakdawalla.bsky.social‬ here:
www.planetary.org/articles/a-m...
...Meanwhile, I had put together the Earth version while I was working in Baku, Azerbaijan:
vimeo.com/195174652
The figure-8 shaped curve you get when you mark the position of the Sun in Earth's sky at the same time each day over one year is called an analemma, as seen in the left hand panel from Baku, Azerbaijan. Shape of the analemma depends on the eccentricity of a planet's orbit and the tilt of its rotation axis, so analemma curves can look different for different worlds. Mars' axial tilt is similar to Earth's, but its orbit around the Sun is more eccentric. As seen by Opportunity rover from Victoria crater in Mars, the analemma traced in the right hand panel is shaped more like a tear drop. Each world's solstices lie at the top and bottom of their respective analemmas.

Retrograde Mars 2024-5
apod.nasa.gov/apod/ap25053...
vimeo.com/1085645909

I photographed Mars every 5 to 9 days between 19th September 2024 and 18th May 2025, while the red planet traced its retrograde loop in Gemini and Cancer.
Mars seems to be going backwards (retrograde) from 8th December 2024 until 24th February 2025, as faster Earth catches up and passes slower Mars. The result is a clockwise loop traced against the constellations of Gemini and Cancer in the course of 8 months.

PS. This is a deserted M-class planet in a dark matter nebula, so we could say, like in a day or two.
