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 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 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.
