V407 Cygni.

NAKANO S. and KOJIMA T.

Abstract (from CDS):

S. Nakano, Sumoto, Japan, reports the apparent independent discovery of this outburst by Tadashi Kojima (Tsumagoi, Agatsuma-gun, Gunma-ken, Japan), who reported it as a possible nova of mag about 7 on two frames taken on Mar. 11.789 UT using a Canon EOS 40D Digital Camera (+ 50-mm f/2.8 camera lens mounted on a Sky-Memo equatorial instrument). Nakano has measured the following position for the variable from Kojima's JPEG image (limiting mag 12.2), upon which the variable is at mag 7.3: R.A. = 21:02:10.18, Decl. = +45:46:30.8 (equinox 2000.0; uncertainty about 8"). Kojima writes that nothing is visible at this position on his survey frames taken on 2010 Jan. 29 (limiting mag 11), Feb. 23, and 24 (limiting mag 12).

The General Catalogue of Variable Stars lists the position of V407 Cyg as R.A. = 21:02:09.9, Decl. = +45:46:33 (equinox 2000.0), noting its observed range to be magnitude 13 to fainter than 17; it may have been a slow nova in 1936, and a Mira-type variable appears involved with this object, as well. Additional spectroscopy is urged to determine the nature of this object, as well as more accurate astrometry.
