Session Notes

C/2011 J2 LINEAR - Comet C/2014 Q3 Borisov - Comet     Nova Del 2013 - Nova (V339 Del) IW And - Variable Star (Z Camelopardalis-type)     Berkeley 4 - Open Cluster     M15 - Globular Cluster     NGC 133 - Open Cluster NGC 1502 - Open Cluster NGC 7510 - Open Cluster  (Herschel VII-44)     Tombaugh 5 Attempt - Open Cluster     Variable Stars (photometric monitoring) - 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    Nearby Stars (astrometric monitoring) - 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°C before climbing to 4°C.  - CCD operation -25°C (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.   - -

Nova Del 2013 - Nova (V339 Del)

Nova Del 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 Alias:  V339 Del

Nova Del 2013 - 2014-11-30 (T+474d) taken 474 days after discovery when nova had faded to around ~ +13.1
