M. Villi reports the discovery by Giancarlo Cortini (Predappio, Italy) of an apparent supernova (mag 16.5) on several unfiltered CCD images (limiting magnitude about 18.5) taken on Jan. 26.75 UT with a 0.35-m telescope at Monte Maggiore; Cortini initially provided only an offset from the center of the galaxy NGC 524 (160" east, 54" north) for the new object, later adding that nothing is present on previous images taken on 2004 Dec. 23.9 (limiting mag 19.0) and 2008 Jan. 1.95 (limiting mag 18.5) or on Palomar Sky Survey red and blue plates (limiting magnitude 21.5). Cortini subsequently provided additional information (via S. Moretti), giving mag 17.3 for 2008Q on Jan. 26.771, and adding that confirming images were taken by other Italian observers at his request: S. Moretti and S. Tomaselli (Bastia, Ravenna) on Jan. 26.812, and G. Cherini (Trieste) on Jan. 27.849 (mag 16.7, via an unfiltered CCD image). At this same time, Cortini provided the following precise position for the new object: R.A. = 1h24m57s.23, Decl. = +9o33'01".5 (equinox 2000.0 presumed), or 141" east and 42" north of the center of the nucleus of NGC 524, adding that the object had not moved some 24 hr later (Jan. 27.86). Cortini has posted finding charts for 2008Q at the following website URL: http://it.geocities.com/gruppoastrofiliforlivesi/524.
