V407 Cygni.

MAEHARA H.

Abstract (from CDS):

Maehara adds that he obtained a low-resolution spectrogram (range 400-800 nm) of V407 Cyg on Mar. 13.842 UT with a 25-cm telescope. The spectrum shows the Balmer series, He I (587.8, 667.8, 706.5 nm), and Fe II emission lines. The FWHMs of H_alpha, H_beta, H_delta, and He I 587.8-nm emissions are 1600, 2400, 2400, and 1600 km/s, respectively. The spectrum can be seen at website URL http://www.kwasan.kyoto-u.ac.jp/~maehara/novae/CYGV407-20100313.png. CCD images obtained with a 25-cm telescope around Mar. 13.83 yield the following magnitudes: Mar. 13.8291, I_c = 5.93; 13.8293, R_c = 7.18; 13.8309, V = 8.83; 13.8309, B = 9.58. Maehara notes that these features suggest that the current unusual brightening of V407 Cyg is caused by a nova outburst in a symbiotic system.
