21:56:45 UTC … maybe a bit off-topic – but very impressive – a IRIDIUM 26 satellite flare with mag -6

A satellite flare is the phenomenon caused by the reflective surfaces on satellites reflecting sunlight directly onto the Earth below and appearing as a brief, bright “flare”. The Iridium communication satellites have a peculiar shape with three polished door-sized antennas, 120° apart and at 40° angles with the main bus. The forward antenna faces the direction the satellite is traveling. Occasionally, an antenna reflects sunlight directly down at Earth, creating a predictable and quickly moving illuminated spot on the surface below of about 10 km diameter. To an observer this looks like a bright flash, or flare in the sky, with a duration of a few seconds. Ranging up to -8 magnitude (rarely to a brilliant -9.5), some of the flares are so bright that they can be seen at daytime; but they are most impressive at night.
