The big #sunspot group (1)4079 could also be, well, detected during a cloudy #sunset over #Bochum, Germany, this evening when it appeared in two narrow and very low slits in a cloud bank. More pictures - also with the Moon high above the drama :-) - in https://www.facebook.com/dan.fischer.393/posts/pfbid02ZqCHxn7hbNBTCV5UsySFHVGergEm55m6fTx1WoUWGrvAoJabTWKS7akTnemKajoDl

The big #sunspot group (1)4079 on 2 May from Bochum, Germany, in daytime and during sunset: many more pictures in https://www.facebook.com/dan.fischer.393/posts/pfbid09KVxx99yBuAn2iW7ZxZLtMW5k4TRmk58dFH66joMDHLsnuP9RbHyG1pPyAHDiKiTl (also with the Moon in detail and near Gemini, Mars near Beehive and a wider view of everything together).

The big #sunspot group (1)4079 minutes ago from Bochum, Germany - as usual easy to see with the naked eye through eclipse glasses.

Cloud gap fun with the big #sunspot group AR (1)4079 - now near the central meridian - today (4 May 2025) in Bochum, Germany: through eclipse glasses in the late afternoon ... and during a super-bright sunset. Rain had cleared the atmosphere so much that in the clear segments even at sunset 1/16'000 second at f/8 and ISO 100 still delivered an overexposed picture! The double umbra is still visible, however, as were nice green effects earlier at the upper rim: more pictures in https://www.facebook.com/dan.fischer.393/posts/pfbid02R62RxXgjbwGuWpKRDRx4Yb8LrkycZ1P5KQJTchaB4ZZzaSa3LzzVVoptyjqvcrRal

The big #sunspot group AR (1)4079 on 6 May 2025 over Bochum, Germany: through eclipse glasses in the afternoon - and through three different horizontal gaps in clouds at sunset! The more detailled sequence https://www.facebook.com/dan.fischer.393/posts/pfbid028Ehr7KqoJQk5wbhzVEHWEXATMjjJiSsR8tvnUtS6LeKXsVsWMMZHvAWocy1gJZbMl also shows green rims at times and a modest sun pillar.

Sunset with crane and #sunspot group (in Bochum, Germany, on 9 May 2025) - the AR (1)4079 can be seen near the solar limb in the '4:30' position: many more pictures, also of the group during the day on 7, 8 and 9 May, in https://www.facebook.com/dan.fischer.393/posts/pfbid0t9AEB6TLtSu29hFTbb3EGR3uW7EQCWqGavkbCxbbBvoTy9pedQheFozxbhXSgrQHl

The #sunspot group AR (1)4079 right at the limb of the Sun during sunset on 10 May - there wasn't enough 'natural filtering', so even at 1/16,000 second at f/8 and ISO 100 the Sun was burned out, but the group is right there: full sequence (with earlier day time images and the Moon) in https://www.facebook.com/dan.fischer.393/posts/pfbid02tJDxMAUgBwBeXa8aV2Hhpjc4BTdwmQUm98DagqiviTygCCnDrdKH6qjivRW4y6Phl

With the big #sunspot gone from the disk little is happening ... so here's the #sunset with a #swift from yesterday. In https://www.facebook.com/dan.fischer.393/posts/pfbid0uDCAnPLqQ8J4pPmMhSoTCtzoH5ZLWtngukALSjrraiTdfgBCq76KFqhJMJsxyHYpl more pictures from the last three days, just for the record.

Yep, that - the dark splotch near the top of the setting Sun in the unobstructed area - is the #sunspot group (1)4087 ... which produced an X2.7 #flare today despite looking completely harmless in white light: https://www.facebook.com/photo/?fbid=1087060393447823 and https://x.com/JAtanackov/status/1922592737762968049 (pic as usual from #Bochum, Germany; minutes ago).

The #sunspot group (1)4087 - the black dot above the trees - during today's #Bochum #sunset ... it was clearer than yesterday so even at the very shortest possible exposure, 1/16,000 sec at f/8 and ISO 100, the Sun was still significantly overexposed. Meanwhile the sunspot itself is taking a nap and produced only an M and a few C flares today but its magnetic structure allegedly keeps having a potential for more.

The #sunspot group (1)4087 just above a cloud band during the Bochum #sunset today - followed by a pretty pronounced #GreenRim of the Sun, not seen in the days before.
