Session Notes

IW And - Variable Star (Z Camelopardalis-type) C/2014 Q3 Borisov - Comet C/2011 J2 LINEAR - Comet Nova Delphini 2013 - nova M15 - Globular Cluster NGC 7510 - Open Cluster NGC 133 - Open Cluster Berk 4 - Open Cluster NGC 1502 - Open Cluster Tombaugh 5 Attempt - Open Cluster     Photometric Monitoring - Variables - IW And, RX And, W And, CI Cyg, S Cyg, SS Cyg, AM Her, BL Lac, DY Per, GK Per, UV Per, FG Sge, V Sge, WZ Sge      Astrometric Monitoring - Nearby Stars - Ross 248 (HH And), 61 Cyg, Groombridge 34, EV Lac

- Evening session (3.5 hrs duration).   Very good seeing, almost windless. Moonlight and high thin cloud. Cloud increasing reducing transparency untill session aborted. (Possibly prematurely as cloud cleared again) - Session operated under semi-automated control, with remote monitoring from indoors computer.   - Ambient Temperature:  Temperature fell to minimum of 1.5 degC before climbing to 4 degC.  - CCD operation -25 degC (at 66% 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.   - -

IW And - Variable Star (Z Camelopardalis-type)

IW And (Andromeda) CVnet reports that this star is in outburst GCVS Catalog :  Type UGZ, Mag Range +13.7 to +17.3 The approximate magnitude in the image below is +14.1 (C) which confirms an outburst

 Nova Delphini 2013 - nova

Nova Delphini 2013 (Delphinus) Nova Delphini was discovered on 14th August 2013 by Japanese observer Koichi Itagaki at magnitude +6.8.  Koichi had imaged the same field the day before and nothing was visible at the same location. The progenitor star was identified from archive images as being magnitude +16.9 The image below was taken 474 days after discovery when the nova had faded to around +13.1
