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. This AAVSO Special Notice was prepared by M. Templeton. --------------------------------------------------- SUBMIT OBSERVATIONS TO THE AAVSO Information on submitting observations to the AAVSO may be found at: http://www.aavso.org/observing/submit/ SPECIAL NOTICE ARCHIVE AND SUBSCRIPTION INFORMATION A 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/
