SUPERNOVA 2004cv IN MCG +03-41-120
ON 2004 June 25 we received an e-mail from Mark Armstrong of Rolvenden, 
England in which he reported his discovery of a possible supernova in 
magnitude 16.8 in the galaxy MCG +03-41-120 during the course of the UK 
Nova/Supernova Patrol. The following position was derived from 
astrometry of the CCD unfiltered exposure secured with a 0.35-m 
Schmidt-Cassegrain telescope:

2004 06 24.96907UT  RA 16h 06m 14.47s DEC +18 24 53.9"(2000).
Limiting magnitude of discovery image was 19.0.
25.3123 RA 16h 06m 14.42s DEC +18 24'54.1"(2000)
Offsets 1" west, 2" north.

There is no trace of the suspect on Mark's images of 2004 May 18, 24 and 
June 8 (all limiting magnitude 19.0) nor on the POSS-II red 1987.308 (LM 
20.8) and blue 1992.419. A 1991 POSS-II `infra-red` plate was also 
negative (LM about 20.0).

A later e-mail received on June 25 advised that Mark had obtained 
confirmation with astrometry giving end figures RA 14.48s DEC 53.9".

The object has been designated supernova 2004cv and announced on IAUC 
8362.

Congratulations to Mark on the discovery of his 66th supernova.
