Objects Session Notes
22P/Kopff - Comet NGC 4361 - Planetary Nebula NGC 5023 - Spiral Galaxy NGC 5227 - Spiral Galaxy with SN ASASSN-15fz UGC 8313 - Spiral Galaxy UGC 8683 - Irregular Galaxy 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°C - CCD operation -25°C (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.
