Session Notes

UV Per - Variable Star     Hickson 5 - Galaxy Cluster (NGC 190) Hickson 8 - Galaxy Cluster (PGC 2886 et al) Hickson 45 - Galaxy Cluster (PGC 30153 et al)     NGC 2771 - Spiral Galaxy with Supernova ASASSN-14iu NGC 5229 - Spiral Galaxy (M51 Group) NGC 6842 - Planetary Nebula     UGC 11919 - Spiral Galaxy   Variable Stars (photometric monitoring) - RX And, U And, W And, Z And,  TT Ari, CI Cyg, S Cyg, SS Cyg, U Gem, CZ Ori, RU Peg, DY Per, GK Per, UV Per, FG Sge, V S     Nearby Stars (astrometric monitoring) - Ross 248 (HH And), Groombridge 34, Teegradens Star

- Evening session (4.7 hrs duration).   - Session operated under semi-automated control, with remote monitoring from indoors computer.   - Ambient Temperature:  Temperature fell to minimum of 1°C before climbing to 3.5°C at mid-night - CCD operation -25°C (at 61% 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.   - -

UV Per - Variable Star (SS Cygni-type)

UV Per (Perseus) CVnet reports that this star is in outburst GCVS Catalog :  Type UGSS, Mag Range +11.0 to +17.5 My original interpretation of the image below was "The approximate magnitude in the image below is    +9.9 (C) which confirms an outburst". This assumed however that the catalog position for UV Per was correct in TheSky !.

UV Per - Later Re-Assessment

After seeing a recent 2018 image the earlier 2014 image is considered to indeed show UV Per at outburst but at the position marked by the white indicator, rather than at the catalog position indicated by TheSky6 [ Detailed AAVSO Star Chart for UV Per confirms this correct position]

UV Per - Later Image (2018) UV Per believed to be in its normal dim (non-outburst) state (mag +17 or so)

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 42 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
