Session Notes

P/2014 L2 (NEOWISE) - Comet     NGC 201 - Spiral Galaxy NGC 2771 - Spiral Galaxy with Supernova ASASSN-14iu NGC 7673 - Spiral Galaxy     UGC 8331 - Irregular Galaxy (M51 Group) (Attempt) UGC 11919 - Spiral Galaxy   - C2014 E2 (Jacques) attempt failed (due to poor seeing)   Variable Stars (photometric monitoring)   - RX And, U And, W And, Z And,  TT Ari, CI Cyg, SS Cyg, S Cyg, U Gem, AM Her, BL Lac, CN Ori, CZ Ori, FO Ori, FU Ori, NV Ori, RU Peg, DY Per, GK Per, FG Sge, U Sge, V Sge, WZ Sge     Nearby Stars (astrometric monitoring)   - Ross 248 (HH And), 61 Cyg, Groombridge 34, EV Lac, Teegradens Star

- Evening session (5.2 hrs duration).   - Session operated under semi-automated control, with remote monitoring from indoors computer.   - Ambient Temperature:  0.5°C minimum - CCD operation -25°C (at 62% average cooling).  - main objectives of the session was to monitor selected variable stars & nearby stars and to take gallery images of a range of deep sky objects.  (Poor sky conditions & moonlight hindered attempts to get any good images) - -
