Session Notes

NGC 4361 - Planetary Nebula 22P/Kopff - Comet NGC 5023 - Spiral Galaxy UGC 8313 - Spiral Galaxy UGC 8683 - Irregular Galaxy NGC 5227 - Spiral Galaxy with SN ASASSN-15fz     Photometric Monitoring - Variables   SY Cnc, RZ LMi, R CrB, U Gem, DY per, GK Per, RR Tau, ER UMa     Astrometric Monitoring - Nearby Stars   None

- Evening session (2.2 hrs duration).   Clear sky. An aurora display began later on at 1:30am. - Session operated under semi-automated control, with remote monitoring from indoors computer.   - Ambient Temperature:  minimum of +4.5 degC - CCD operation -25 degC (at 76% average cooling).  - Main objectives of the session was to monitor selected variable stars & nearby stars and to take gallery images of a selected deep sky objects  (including several members of the M51 Galaxy Group)      - Notes: RZ LMi images (90s, C filter, -25deg C) wouldn't link until after a Hot Pixel repair operation is performed.
