Session Notes

17P/Holmes - Comet 108P/Ciffreo - Comet 110P/Hartley - Comet     NGC 2771 - Spiral Galaxy with Supernova ASASSN-14iu NGC 5229 - Spiral Galaxy (M51 Group)   Variable Stars (photometric monitoring) - FO And, RX And, U And, W And, Z And, TT Ari, FS Aur, R CrB, CI Cyg, SS Cyg, S Cyg, U Gem, AM Her, BL Lac, SZ Lyn, CN Ori, FO Ori, FU Ori, IP Peg, RU Peg, DY Per, GK Per, FG Sge, V Sge, WZ Sge, RR Tau, SU Tau, ER UMa - U Sge attempt failed (unable to link/plate solve) Nearby Stars (astrometric monitoring) - Ross 248 (HH And), 61 Cyg, Groombridge 34, EV Lac, Teegardens Star

- Evening session (6.6 hrs duration).   - Session operated under semi-automated control, with remote monitoring from indoors computer.   - Ambient Temperature:  +5°C minimum - CCD operation -25°C (at 73% 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 largely prevented getting any good images) - -

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 21.3 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

Annotated CCD Image (cropped) 5 x 60 sec exposure (average combine), 3x3 binning, C Filter 2014-11-02 21:47hUT (#567194-98) 12" LX200R  (at f/10.4) + ST-10XME

NGC 2771 with supernova ASASSN-14iu - earlier image (2014-10-28) Taken 16.3 days after discovery ,  combined measured brightness of supernova + galaxy center is +12.8
