Nova Cygni 2014 (was PNV J20214234+3103296: possible nova in Cygnus) – 1 Apr. 2014
NB: this transient was officially named “Nova Cygni 2014” in the CBET 3842 (subscription required), including our prompt follow-up!
Late on 31 Mar. 2014, a possible nova in Cygnus, temporary designation PNV J20214234+3103296, was reported by CBAT, discovered by Koichi Nishiyama, Kurume,Japan and Fujio Kabashima, Miyaki, Japan.
On 1.1 Apr. 2014, just a few hours later, at Virtual Telescope, G. Masi, F. Nocentini e P. Schmeer provided fast optical and, most importantly, spectroscopic observations of the transient, confirming it and discovering the presence of H-alpha emission, suggesting the nova nature of the object.
Astrometry follows (J2000.0, residuals around 0.1″):
RA: 20 21 42.32 Decl.: +31 03 29.4
Magnitude on 1.1034 Apr. 2014: 11.0 (unfiltered, R mags for the reference stars from UCAC-4 were used).
Below, a chart is available, showing where this new transient is placed in the sky.
