Special Notice #157: Possible Nova in Centaurus [V1213 Cen; Nova Cen 2009]

AAVSO Special Notice #157

Possible Nova in Centaurus
May 13, 2009

G. Pojmanski of the ASAS Project has announced a possible nova in Centaurus in vsnet-alert 11243.  The object [V1213 Cen; Nova Cen 2009] was first detected on 2009 May 08.235 (JD 2454959.735) at a V magnitude of 8.533, and was at around V ~ 9.13 on 2009 May 11.14 (JD 2454962.64).  Pojmanski gives the following coordinates for the nova:

RA: 13 31 16 , Dec: -63 57.6 

These coordinates are accurate to approximately 4.0 arcseconds rms, and so the position of the progenitor cannot be determined exactly.

Follow-up observations -- particularly astrometry and spectroscopy -- are strongly encouraged.  Further Special Notices will be issued when the coordinates are refined, and an AAVSO Alert Notice [AAVSO Alert Notice 396] will be issued if the object is conclusively classified as a nova.  Please hold photometry until the object is entered into VSX (which requires accurate coordinates). Please email astrometric measurements to aavso at aavso.org as soon as they are available.
