NOVA SCO 2014

Koichi Nishiyama and Fujio Kabashima, Japan, report their discovery of a magnitude 10.1 nova in Scorpius using an unfiltered CCD and a 105-mm-f.l. f/4 camera lens on 2014 Mar. 26.8487 UT.  The coordinates are: R.A. 17 15 46.83 Dec. -31 28 30.3 (2000.0).

NOVA CYG 2014

Koichi Nishiyama and Fujio Kabashima, Japan, further report theirdiscovery of a magnitude 10.9 nova in Cygnus using an unfiltered CCD and a 105-mm-f.l. f/4 camera lens on 2014 Mar. 31.790 UT. Coordinates: R.A. 20 21 42.32, Decl. +31 03 29.4 (2000.0).  Nothing is visible at this position on their past survey frames taken on Mar. 27.781 (limiting mag 13.4) or on the Digitised Sky Survey, but it is apparently visible at mag 12.4 on a pre-discovery image (limiting mag 13.5) taken on Mar. 30.769 UT.

Ulisse Munari, Istituto Nazionale di Astrofisica, Padova Astronomical Observatory et. al., report that on Apr. 1.060 UT they obtained a medium-resolution spectrogram which is that of a classical nova close to maximum brightness and appreciably reddened.  On Apr. 1.099, they obtained the following photometry for Nova Cyg 2014: B = 12.28, V = 11.32, R_c = 10.68, I_c = 10.03. The large B-V colour supports a significant reddening affecting this nova.
