(2010 outburst)

August 28, 2010 update

Very bright outburst of symbiotic star V407 Cyg. This outburst was discovered independently by the team of K. Nishiyama (Fukuoka, Japan) and F. Kabashima (Saga, Japan), and by T. Kojima (Tsumagoi, Agatsuma-gun, Gunma-ken, Japan). Nishiyama and Kabashima observed the star at an unfiltered magnitude of 6.8 on 2010 March 10.813 (JD 2455266.313) and magnitude 6.9 on 2010 March 10.814 (2455266.814). Kojima observed the star at around magnitude 7 on two images taken using a Canon EOS 40D (CBET 2199). The spectra exhibiting spectral features clearly indicating a classical nova of the He/N type (see CBET 2204). R.A. = 21h02m09s.85, Decl. = +45°46'10'33.0" (equinox 2000.0).

V407 Cyg lines identification by François Teyssier.
