Objects	Session Notes
C/2020 V2 (ZTF) - Comet     -  Imaging of IC 1874 w/SN2023fu failed (frames rejected due to cloud/bad guiding)     Variable Stars (photometric monitoring) - None      Nearby Stars (astrometric monitoring) - None	- Very short session (0.9 hours) due to cloud. Cloud delayed start of session and then skies became cloudy again less than 1 hour into the sessions and remained overcast until dawn     - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: 1.5°C (min) - CCD Temperature:   -20°C - Notes from 2023-03-02 >>
