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 - 2013-10-11 (T+59d) taken 59 days after discovery when nova had faded to around +9.5
