Session Notes

UGC 11919 - Spiral Galaxy NGC 7673 - Spiral Galaxy P/2014 L2 (NEOWISE) - Comet NGC 2771 - Spiral Galaxy with Supernova ASASSN-14iu   Photometric Monitoring - Variables - RX And, U And, W And, Z And,  FS Aur, R CrB, CI Cyg, SS Cyg, S Cyg, AM Her, BL Lac, RU Peg, DY Per, GK Per, FG Sge, U Sge, V Sge (TT Ari, U Her, WZ Sge failed - no link) Astrometric Monitoring - Nearby Stars - Ross 248 (HH And), Groombridge 34, EV Lac (Teegardens Star failed - no link)

- Evening session (4.5 hrs duration).   - Session operated under semi-automated control, with remote monitoring from indoors computer.   - Ambient Temperature:  -0.5 degC minimum - CCD operation -25 degC (at 58% 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) - -

P/2014 L2 (NEOWISE) - Comet

P/2014 L2 (NEOWISE) (Passing through starfield in Aquarius.  Sun Distance 2.46 AU) Comet is probably not visible in this image. Expected Comet position is marked by the white circle. The white indicators show a probable star.  A future image is required to confirm this

NGC 2771 - Spiral Galaxy with Supernova ASASSN-14iu

NGC 2771 with supernova ASASSN-14iu (Ursa Major) ASASSN-14iu (Type Ia,  z=0.016855) was discovered 2014/10/12.610  by All Sky Automated Survey for SuperNovae (ASAS-SN) at magnitude +15.8 Located 1.3" west and 0.8" north of the center of NGC 2771 (Rochester Supernova site | Discovery Image ) The image below was taken 24.3 days after discovery  The supernova position is indicated by white markers. The image is unable to resolve the Supernova separately to the galaxy centre. The combined measured brightness of supernova + galaxy center is +13.0
