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.

The image above was remotely taken with the PlaneWave 17″ robotic unit, while the spectrum below was remotely captured with the Celestron c14 robotic unit, using a 100 lines/mm diffraction grating.
