SUPERNOVA 1997eg IN NGC 5012
S. Nakano, Sumoto, Japan, reports the discovery by Masakatsu Aoki,
Tsukioka-cho, Toyama, of an apparent supernova (mag 15.6) on
ten frames taken around Dec. 4.85 UT and three frames taken on Dec.
5 with a 0.43-m f/6 reflector (+ unfiltered CCD).  The limiting
magnitude on Dec. 4 was about 18.5.

SN 1997eg is located at R.A. = 13h11m36s.73, Decl. = +22o55'29".4
(2000), which is 4".1 west and 33".1 north of the centre of
NGC 5012.  There is no object at this position on Aoki's earlier
frames taken on fifteen nights between 1996 Apr. 22 and
1997 Aug.11, or on the Digital Sky Survey. There is a star of mag
13.9 located about 5" east of SN 1997eg.
