SUPERNOVA 2003jz IN UGC 5225
On 2003 November 18, an e-mail was received from Mark Armstrong of
Rolvenden, Kent reporting that he had recorded a possible supernova
in the galaxy UGC 5225 during the course of CCD imaging for the UK
Nova/Supernova Patrol. 

The new object, of magnitude 17.5, was first noted on an unfiltered
image of 2003 Nov 13.180UT using a 0.35-m Schmidt-Cassegrain
telescope and confirmed on Nov 17.126UT, both frames having a
limiting magnitude of 19.5. Mark subsequently noted it was present
on Oct 17.153UT at magnitude 16.0 but initially missed as it was
close to the core of the galaxy.
 
The new object is located at:
RA 09h 46m 28.67s DEC +45 45'04.7" (2000), approximately 1"E and 4"
S of the centre of host galaxy. Nothing was visible on a LOSS/KAIT
image taken on 2002 Nov. 30 (limiting mag. about 19.0) and on
Palomar Sky Survey red and blue plates.

The object has subsequently been designated Supernova 2003jz and
announced on IAU Circular 8241.

This find marks a major landmark in the series of supernova
discoveries by Mark as this is his 50th since the first detection
back in 1996. We offer congratulations on both this latest find and
also reaching 50 discoveries.
