SUPERNOVA 2002cs IN NGC 6702
Mark Armstrong, Rolvenden, England advises us that he recorded a
possible supernova of magnitude 16.3 in NGC 6702 on a single 45
second duration image of 2002 May 5.133UT (limiting magnitude 18.5)
using a 0.36-m Schmidt-Cassegrain telescope + ST9 CCD (unfiltered)
during searches for the UK Nova/Supernova patrol. The discovery
image was obtained just 5 minutes before cessation of the patrol
due to morning twilight.

He derived the following position:
RA 18h 46m 59.95s DEC +45 42' 20.2" (2000) and estimated the
offsets as 1"N and 24"E of the nucleus. 

Mark was unable to trace the suspect on a master image of 60
seconds duration obtained on 2000 Nov 12 with a similar telescope. 
He further noted it was absent from POSS-II blue, red and infrared
images.

Dan Green, Central Bureau, has reported on IAUC 7891 that he
received an independent discovery report from the LOTOSS team who
recorded the new object on May 5.5 at about magnitude 15.9 whereas
on a KAIT image of 2001 October 3.2UT it was fainter than 19.0. The
designation of SN 2002cs was therefore announced on the same IAUC.

Congratulations to Mark on this latest discovery.
