POSSIBLE NOVA IN CYGNUS
Akihiko Tago, Japan, has reported the detection of a possible nova of 
magnitude 7.4 on three 30 second CCD exposures taken around 2007 Mar. 
15.78UT using a Canon 20Da digital camera with 70mm lens.

The images, which reach a limit of about magnitude 13.2, allowed Tago to 
measure a position of:
RA 20h 28m 15s DEC +41 49.0' (2000).

An image of March 12.796UT, limiting magnitude 12, does not show an 
object in this position but on Mar 16.75 it was recorded at about 
magnitude 7.5.

Nakano reports  that K. Nishiyama and T. Sakamoto, Bisei Spaceguard 
Center, have confirmed the variable object at mag 6.7 on an unfiltered 
CCD image taken with the 1.0-m f/3.0 reflector on Mar. 16.768, giving 
the object's position end figures as
RA 12.52s, DEC 48'36.5"(2000). A red USNO-catalogued star is located at 
position end figures 12s.505, 48'36".69 (red mag 18.5).
