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.🗿🙂 www.wgsbn-iau.org/files/Bullet...
APOD 82 Retrograde Neptune & Saturn 2025-6 apod.nasa.gov/apod/ap260506.html 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.
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.
APOD 81 & 53 2 Total Lunar eclipses of Saros 133 apod.nasa.gov/apod/ap26030... 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.
APOD 80 Twilight With Moon and Planets antwrp.gsfc.nasa.gov/apod/ap26022... 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.

It's Harrison Ford's birthday today, thus we are contractually obligated to point you to this ridiculous classic from our archives.
APOD 79 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
This one aged well. Well, really slowly...😉

APOD 78 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.
@nocontexttrek1.bsky.social I reckon he will be weaving a new one in no time.😏 PS. This is a deserted M-class planet in a dark matter nebula, so we could say, like in a day or two.

Here is a Best 9 comet selection, as seen by SOHO LASCO C3.☄️ PS. Comets NEAT and Bradfield were suggested by @sungrazercomets.bsky.social in October 2024.
Comet C/2024 G3 Atlas is barely visible against bright twilight with Mercury shining at mag. -0.4. This view is from a 500-meter-high hilltop near Çepni village, about 30 km northwest of Bursa, Turkey. 0748 GMT+3, 10th January 2025.
At last, aurora is visible from Bursa, Turkey. An X-class Solar flare and accompanying CME delivered aurora as far south as Bursa, Turkey, 40d N on 10-11 October. This look at north from 1730-meter-high Bakacak peak of Uludağ NP finds red aurora shining over Bursa, and even İstanbul 100 km away.
APOD 77 5 comets from SOHO apod.nasa.gov/apod/ap24101... A selection of 5 comets, as seen by SOHO Lasco C3 coronagraph. This has been the first time my name appears with an APOD, which I did not actually photograph.
APOD 76 Mars, Uranus, Pleiades apod.nasa.gov/apod/ap24080... I photographed Mars for 16 days between 12-27 July 2024, as it passed by Pleiades, and also greenish Uranus which is moving much slower in the sky. I started photography at Mt. Sandras in Denizli, then completed imaging in Bursa, Turkey
APOD 75 Solstice Moon apod.nasa.gov/apod/ap24062... Full Moon of 21-22 June 2024 occurred within 28 hours of the solstice. I set up a camera at my rooftop in Bursa, Turkey to photograph the Moon every 10 minutes, which stayed less than 7 hours in the sky and rose only 22 degrees at local midnight.
