V2362 CYGNI = POSSIBLE NOVA IN CYGNUS
N. N. Samus, Russian Academy of Sciences, advises us that this possible 
nova (cf TA E-Circular 2216) has been assigned the designation V2362 
Cyg.

Daisaku Nogami, Japan, reports via VSNET (Alert 8902) that M. Fujii 
obtained a low-resolution optical spectrum of the possible nova in 
Cygnus on April 5. A clear P Cyg profile was seen in the Halpha region. 
The FWHM of the emission component was ~500 km/s, and the bottom of the 
absorption component was 15A bluer than the emission peak.  The other 
Balmer lines (Hbeta, Hgamma, and Hdelta) were seen in pure absorption, 
possibly due to the resolution of his spectrograph.  The EW of the Na D 
absorption was 3A.  Based on these features, he commented that this 
object seems to be a nova at the maximum brightness.

Guy Hurst, Basingstoke, England, reports that the nova was recorded on a 
30 second exposure (400 ISO) at extremely low altitude and moonlight, 
using the survey camera Canon 10D + 85mm lens during searches for the UK 
Nova/Supernova Patrol. On April 5.945UT the magnitude was estimated at 
magnitude 8.5 (Tycho stars as comparison).

Mike Collins, Everton, Bedfordshire, England, advises that two 3-minute 
shots obtained for the UK Nova Patrol on 2006 March 4 do not show the 
object to a limit of magnitude 12 using the Canon 10D + 85mm lens f1.8. 
Using similar equipment on April 6.0831UT Mike estimated the nova at 
magnitude 8.6.

Gary Poyner, Birmingham, e-mails a visual estimate:
Apr 06.125     8.2    0.22-m    Seq.  AAVSO 060405
