AAVSO Special Notice #55

Possible Nova in Vul
August 8, 2007

CBET 1027 reports that Hiroshi Abe has discovered
a new bright nova around August 8, at coordinates
19:54:24.64 +20:52:51.9 J2000
and with brightness V=9.4mag.  A possible progenitor
star is visible on the POSS-I survey plates at
about V=18.

This sounds like an ideal target for northern observers.
You can plot the field using VSP:
http://www.aavso.org/observing/charts/vsp/index.html
and entering the coordinates given above.  This is about
7arcmin from SS Vul, a Mira that is not on the AAVSO
program.  We will create a sequence for the new nova
as soon as possible.

August 9, 2007

N Vul 07 (CBET 1027, AAVSO Special Notice #55) is most likely a nova;
high-resolution spectra are being analyzed to confirm the object's nature.
An AAVSO Alert Notice will be issued later, but the purpose of this special
notice is to inform observers that:

- N Vul 07 (19:54:24.64 +20:52:51.9 (2000.0)) has been added to the AAVSO
files as 1950+20 N VUL 07.
- An AAVSO chart with photometry by Richard Miles may be obtained from the
AAVSO Variable Star Plotter (VSP) by going to
http://www.aavso.org/observing/charts/vsp/
and entering 1950+20 or N VUL 07.
- Observations reported to the AAVSO indicate that N Vul 07 is continuing
