Another #Bochum (Germany) #sunset today - and numerous times a tiny #GreenSegment separated from the disk: here are two pictures each of two such cases.

Third #Bochum #sunset in a row, on 24 August, now perfectly clear - the Sun right *on* the horizon was way too bright to look at - and with obvious #sunspots: according to https://spaceweather.com/images2026/24aug26/hmi1898.gif these are the activity regions (1)4513 and 4517.
