SUPERNOVA 2003da in UGC 4992
On April 7, we received an e-mail from Tom Boles, Coddenham,
England, reporting a possible supernova in UGC4992. This was
present on multiple images but on a single night (April 6). First
detection was on an unfiltered image of April 6.898UT using a
0.35-m reflector during the course of searches for the UK
Nova/Supernova Patrol. The new object, of magnitude 15.9, is
located at: RA 09h 23m 47.56s DEC +42 10'48.6" which is
approximately 1".8 W and 12".0 S of the centre of UGC 4992. The
suspect is not present on Tom's images of 2003 Feb. 02 (limiting
mag 19.0) and March 02, and it is not present on Palomar Sky Survey
red (1990.064) and blue plates (1995.894).

Tom obtained a confirmatory image on April 7.834UT with end
figures: RA 47.54s DEC 48.3"

The object was announced on IAUC 8108 as Supernova 2003da.
Congratulations to Tom on the discovery of his 43rd supernova.
