AAVSO Special Notice #85

Possible Nova in Vul
December 26, 2007

The CBET Unconfirmed Observation page at
http://www.cfa.harvard.edu/iau/unconf/cbat_unconf.html
has listed a new object in Vulpeculae at
19:48:08.8  +21:15:23 J2000
The discovery magnitude on December 25.354 was 8.7;
the discoverer is not listed.  No minor planets are
visible in this field according to the minor-planet
checker.

Subsequent observations by VSNET (vsnet-alert 9780)
give magnitudes around V=7.9.  The colors do not
indicate Halpha emission, and the object appears
F-like (or else reddened) at this time.

USNO-B lists an R-band detection at

1112-0430634 19 48 08.87 +21 15 26.8
with a magnitude around 20; no other object is close
to this position in this or other catalogs.
With a very large amplitude, and
lying in the plane of the Milky Way, this is a likely
nova.  Unfortunately, this field is in poor position
for monitoring, so an extended light curve is unlikely.
Place it on your observing program for as long as
you can, and expect to pick it up on the other side
of the Sun.
