Problems:
23:38 CLT while observing TIC121092916, telescope moved in DEC first to S, I recentered, then it moved to N, around 5" each time. I heard the noise of the drives (a decreasing pitch) maybe the same DEC belt that failed time ago is failing again? Added 60 seconds to compensate.

Night started with some cirrus all around, the first quarter ended with only some thin clouds. Second quarter ended practically clear (though there are some clouds at low elevation, below 30 degrees elevation.)
No time for: RKS 0909+0512, RKS 0930+1036A, RKS 1026-0631. Also, I did only 2 * 900 s integrations of TIC71880453 (instead of the 3 * 1200 s requested.)
Last integration completed with the Sun at -9 degrees of elevation!
T in the range 11.5 - 15 C; RH 45 - 75 % ; Wind 1 - 4 m/s. Last 2 quarters of the night, clear though likely hazy.
