AAVSO Alert Notice 498
Nova Cephei 2014 = TCP J20542386+6017077
March 10, 2014

Event: Nova Cephei 2014 = TCP J20542386+6017077

Discovered by: Koichi Nishiyama (Kurume, Japan) and Fujio Kabashima (Miyaki, Japan)

Discovery magnitude: unfiltered CCD magnitude 11.7, using a 105-mm f/4 camera lens + SBIG STL6303E camera

Discovery date: 2014 Mar. 8.792 UT

Coordinates: R.A. 20 54 23.75 Dec. +60 17 06.9 (2000.0). Coordinates from Seiichiro Kiyota (Kamagaya, Japan) from his image taken Mar. 9.244 UT remotely using an iTelescope 0.15-m f/7.3 refractor near Nerpio, Spain

Spectra: Low-resolution spectra obtained by U. Munari (INAF Astronomical Observatory of Padova) and A. Milani, P. Valisa, F. Castellani, and R. Belligoli (ANS Collaboration) on 2014 Mar. 9.792 indicate Nova Cep 2014 is a highly reddened Fe II-type classical nova near maximum. Spectroscopy details may be found in CBET 3825 (see Note a below).

Observing recommendations: Observations of all types (visual, CCD, DSLR, spectroscopy) are strongly encouraged in following the evolution of this nova.

Charts: Charts for Nova Cep 2014 may be created using the AAVSO Variable Star Plotter (VSP).
