Objects Session Notes
C/2022 E2 (ATLAS) - Comet C/2022 N2 (PANSTARRS) - Comet AT 2022vdr - CV Type Transient M31 - Spiral Galaxy with Extragalactic Nova AT 2025nsa (non-detection) M33 - Spiral Galaxy with Transient AT 2025mmr (non-detection) UGC 4973 - Spiral Galaxy with Type IIb Supernova 2025ovr Variable Stars (photometric monitoring) - Z And, TT Ari, SS Cyg Nearby Stars (astrometric monitoring) - None
- Post-midnight session (3.2 hr). Start delayed by cloud - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature : 10°C (min). Temperature fell from 14.5 to 11°C during session with distinct corresponding change to telescope focus. - CCD Temperature: -10°C - Notes from 2025-08-29 >> -
