J. Rudy, The Aerospace Corporation and others report on CBET 2055 0.9- to 2.5-micron spectroscopy obtained on 2009 Nov. 26.4 UT which suggests that this object (cf TA E-Circular 2598) may be a nova of the helium/nitrogen type. Various observers also report the object was brighter at earlier dates than at discovery including "Pi in the Sky' automated equipment which recorded it at magnitude 5.8 on Nov 14 (unfiltered). It is possible observers obtaining images for their Leonid watch may also have recorded it pre-discovery. Please send any images to the editor for analysis. SUPERNOVA 2009jf IN NGC 7479 (OR BLUE LUMINOUS VARIABLE?) Discovery by LOSS of a possible supernova (CBET 1952): SN 2009 UT R.A. (2000.0) Decl. Mag. Offset 2009jf Sep 27.33 23 04 52.98 +12 19 59.5 18.0 53.8"W,36.5"N Photometry by Guy Hurst, Basingstoke, using the Bradford Robotic Telescope suggests the object has brightened considerably since discovery. Using unfiltered imaging in galaxy mode: Oct 23.019UT, 14.5C; Nov 2.9993UT 15.0C. Further results are still being analysed. K. Itagaki et. al., Japan report that a dim spot has been observed near the position of 2009jf on several images in the past few decades. It was detected twice on Itagaki's archived unfiltered CCD images taken with a 0.60-m reflector: 2006 Nov. 8.499 UT, at magnitude about 18.2 (position end figures 53s.08, 58".8), and 2007 Aug. 13.740, at mag about 18.3 (position end figures 53s.00, 59".1). Digitized Sky Survey images at several epochs also show this object, including on 1953 Aug. 19.426, at mag about 18 (O plate), and on 1992 Aug. 2.397, at mag about 18 (J plate). Adopting m-M = 32.55 (Tully, 1988, "Nearby Galaxy Catalog"), its absolute magnitude is -14.5 or so, which strongly suggests that these may be recurring outbursts of a luminous blue variable.
