SUPERNOVA 2010hf IN MCG +09-11-21
T. Boles, Coddenham, England, reports the discovery of an apparent
supernova (mag 18.3) on unfiltered CCD images taken on Aug. 31.114 and 31.894
with a 0.35-m reflector. The new object is located at R.A. = 6h37m19s.77
+/- 0s.02, Decl. = +56o22'57".8 +/- 0".2 (equinox 2000.0), which is
approximately 5".6 west and 11".8 north of the center of MCG +09-11-21.
Nothing is present at this position on Boles's images from 2010 Mar. 2 and
2009 Sept. 25 (limiting mag 19.5) or on Digitized Sky Survey plates from 1991
Feb. 8 (limiting red mag 20.5) and 1991 Dec. 12 (limiting blue mag 21.0).
NOTE: These 'Central Bureau Electronic Telegrams' are sometimes
superseded by text appearing later in the printed IAU Circulars.
