Super-weird #sunset on April 23 from Bochum, Germany, at extreme magnification (optical & digital zoom at the limit, otherwise out of cam, images covering just 3 seconds): the Sun is almost gone, with one half of the remaining segments turning bright green before fading away while the other half is dissolving into a turbulent red cloud ... can only guess that there is some cooling tower or chimney behind the horizon causing this extreme distortion in a particular azimuth. Always something new ...

Another Bochum #sunset, on April 24: four pictures covering just two seconds in which a separated #GreenSegment is forming and vanishing while weird #schlieren features dominate the disk - I still haven't identified the source but it must be very far away (in another shot distant birds in front of the 'boiling' Sun are sharp). Out of cam and just cropped - the obstruction on the right is a distant house.

Lots of cloudy stuff in front of today's Bochum #sunset but the separation of a segment could be followed nonetheless - probably green but the color got lost. There is also a fresh contrail in front of the Sun; image sequence covering 4 seconds.

The #sunspots today, again using only Nature's filter - the haze was thicker than yesterday but the 'optical quality' was very good once more, with well-defined spots: see https://spaceweather.com/images2026/26may26/hmi1898.gif for their identities.
