AAVSO ALERT NOTICE 291 (October 3, 2001)
1348-63 NOVA CENTAURI 2001 - POSSIBLE NOVA IN CENTAURUS
We have been informed by the Central Bureau for Astronomical Telegrams (IAU
Circular 7726) that William Liller, Vina del Mar, Chile, photographically
discovered a possible nova in Centaurus at magnitude 8.6 on images taken
October 1.010 and 1.011 UT, using Tech Pan film and an orange filter at the
R.A. = 13h 55m.5 Decl. = -64o 16' (2000)
Nothing is seen at the location of the nova down to magnitude 11.0 on films
taken by Liller on Sep. 19.00.
Photoelectric photometry of the new object obtained by A.C. Gilmore, Mount
John Observatory, University of Canterbury, using the 0.6-m f/16 reflector
under unfavorable conditions (thin clouds and bright moonlight) yields the
following data for October 2.415: V = 9.11, U-B = +0.83, B-V = +1.41, V-R =
+0.81, V-I = +1.69, with an airmass of 2.18. Gilmore also reported the
following astrometry: R.A. = 13 h 55 m 41 s.9, Decl. = -64o 15' 48" (equinox
2000), with an uncertainty of <10" in each coordinate.
Additional observations submitted to the AAVSO include: Oct. 2.33 UT, 9.2, A.
Jones, Nelson, New Zealand (via IAU Circular 7726); 2.542, 9.3, A. Pearce,
Nedlands, W. Australia; 2.708, 9.5, L.A.G. Monard, Pretoria, South Africa;
2.9931, 9.4, A. Amorin, Florianapolis, Brazil; 3.510, 9.6, A. Pearce,
Nedlands, W. Australia.
Accompanying is an AAVSO 'd' scale preliminary chart of N Cen 01 prepared by
C. Scovil. Please use this chart to observe this nova, and report your
observations of 1348-63 N Cen 01 to AAVSO Headquarters, making sure to
indicate which comparison stars you used.
Congratulations to Bill on his latest discovery!
