SUPERNOVA 2009es IN IC 1525
On May 24, Tom Boles reported to us that he had found a suspected 
supernova of magnitude 17.5 in the galaxy IC 1525 during the course of 
searches for the UK Nova/Supernova Patrol. IC 1525 also produced the 
supernova 1998cu.

The initial detection was on a single image of 2009 May 24.064UT 
obtained with a 0.35-m Schmidt-Cassegrain telescope. The suspected 
supernova is located at:
RA 23h 59m 14.42s DEC +46 52' 36.9" (2000), which is approximately 14.9" 
west and 44.3" south of the centre of the host galaxy. Nothing is 
present at this position on Tom's images of 2007 Dec 13 and 2008 Jul 30 
(limiting mag 19.5) nor on the Digitised Sky Survey
Plates of 1990 Aug 21 (limiting red mag 20.5), and 1989 Sep 28 (limiting 
blue mag 21.0).

In a follow-up message of May 25, Tom advised that he had succeeded in 
obtaining multiple confirmation images of this object on May 25.056UT at 
magnitude 17.7 with end figures: 14.2s and 36.9".

The discovery has been announced on Electronic Telegram 1812 issued by 
the Central Bureau and the object designated SN 2009es.

Congratulations to Tom on the discovery of his 120th supernova.
