2007IAUC.8800....1L

W. Liller, Vina del Mar, Chile, reports his discovery of a possible nova (mag approximately 8.2) located at R.A. = 11h43m.2, Decl. = -58o03' (equinox 2000.0), appearing on two Technical Pan films taken near Jan. 23.354 UT with an 85-mm-focal-length camera lens and an orange filter. Nothing brighter than magnitude 11.5 was seen at this position on exposures from Jan. 15.36. Nothing is seen at this position on the "Real Sky Digitized Southern Sky Survey", encompassing images made with the 1.2-m Schmidt telescope at Siding Spring (limiting magnitude presumed to be 19 or fainter). B. Heathcote (Australia) reports the following precise position for the new star from CCD images obtained on Jan. 25.708: R.A. = 11h43m10s.33, Decl. = -58o04'04".3 (equinox 2000.0), with magnitudes B = 9.08 and V = 8.59. A low-resolution spectrum by Heathcote shows strong H_alpha emission. P. Schmeer (Germany) reports that this position is very close to a star of red mag 18.4 in the USNO-B1.0 catalogue with position end figures 10s.24, 04".5 and of red mag 17.1 in the Guide-Star Catalogue with position end figures 10s.231, 03".85; the 2MASS catalogue contains an object at position end figures 10s.12, 04".1 (with magnitudes J = 16.6, K = 15.1). E. O. Waagen, AAVSO, forwards a report from P. Nelson (Australia) that gives the same position as Heathcote (presumably re-measured) from a V-band CCD image obtained on Jan. 25.656 (with the new variable star at V = 8.5). Waagen also provides position end figures 10s.34, 04".2 forwarded from C. Stockdale (Victoria, Australia) from an image taken on Jan. 25.611 (the magnitude measured as V = 8.7). Visual magnitude esimates: Jan. 25.031, 8.7 (A. Amorim, Florianopolis, Brazil); 25.529, 8.3 (A. Pearce, Nedlands, W. Australia).
