AAVSO Special Notice #55Possible Nova in VulAugust 8, 2007CBET 1027 reports that Hiroshi Abe has discovereda new bright nova around August 8, at coordinates19:54:24.64 +20:52:51.9 J2000and with brightness V=9.4mag. A possible progenitorstar is visible on the POSS-I survey plates atabout 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.htmland entering the coordinates given above. This is about7arcmin from SS Vul, a Mira that is not on the AAVSOprogram. We will create a sequence for the new novaas soon as possible.Arne---------------------------------------------------SUBMIT OBSERVATIONS TO THE AAVSOInformation on submitting observations to the AAVSO may be found at:http://www.aavso.org/observing/submit/SPECIAL NOTICE ARCHIVE AND SUBSCRIPTION INFORMATIONA Special Notice archive is available at the following URL:http://www.aavso.org/publications/specialnotice/Subscribing and Unsubscribing may be done at the following URL:http://www.aavso.org/publications/email/
AAVSO Special Notice #56N Vul 07August 9, 2007N 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 theAAVSO 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 continuingto brighten:AUG 08.9604 UT, 9.30 CCD (based on USNO A2.0), D.
