SUPERNOVA 2002bn IN UGC 6527
Mark Armstrong, Rolvenden, reports the discovery of a further
supernova on a March 8.180UT exposure with the 0.36-m Schmidt-
Cassegrain telescope during the UK Nova/Supernova Patrol. Although
magnitude 17.0 on the discovery image, Mark subsequently he found
it brighter on an earlier image of Feb 15.948UT at magnitude 16.3.

The measured position is:
RA 11h 32m 39.04s DEC +52 56' 54.2" (2000) which is 10"W and 5"S of
the nucleus of UGC 6527, located in the Hickson 56 group.

A comparison with master patrol images of 2000 Dec 30 and 2001 Dec
10 and 22, did not show the object to about the limit of magnitude
19.0. Similarly the Palomar Sky Survey images of 1993 April 25
(red, limit 20.8) and 1994 Apr 19 (blue, limit 22.5) also did not
show it.

Congratulations to Mark on this further success and the designation
announced on IAUC 7846.

SUPERNOVA 2002bl IN UGC 5499
Further to the discovery note on TA E-Circular 1750, we understand
that Alex Filippenko of University of California, Berkeley and
others have analysed a spectrum obtained with the Keck-I telescope
on March 7 which suggests this is another peculiar type-Ic
('hypernova') similar to the recent object, SN 2002ap, two weeks
after explosion. A more detailed note of the spectral analysis has
now appeared on IAUC 7845.

SUPERNOVA 2002bm IN MCG -01-32-19
Tim Puckett and A. Sehgal, USA, have reported their discovery of an
apparent magnitude 17 supernova on an image of March 6 obtained
with a 0.35-m telescope. The position is:
RA 12h 30m 16.90s DEC -08 23' 34.8" (2000), 11.4"E and 15.0"N of
the nucleus of MCG -01-32-19 according to IAUC 7845.
