SUPERNOVA 2001di IN UGC 3259 (Q2001/237)
On 2001 July 29, Mark Armstrong e-mailed the editor with news of
a single image suspect in UGC 3259 recorded on July 28.1UT. He
followed this up by obtaining 13 x 25 second co-added images
through thin cloud on July 30.0UT also showing the suspect. No
known variable or asteroid could be found and no entry appeared in
the A2.0 catalogue. Whilst the Central Bureau will, in the normal
course, seek a spectrum by way of final confirmation, the following
announcement has appeared in an IAU Circular:

Guy M. Hurst, Basingstoke, England, reports the discovery of an
apparent supernova (mag 17.7) by Mark Armstrong (Rolvenden,
England) on an unfiltered CCD image (limiting mag about 19) secured
for the U.K. Nova/Supernova Patrol on July 28.090 UT with a 0.36-m
Schmidt-Cassegrain telescope.  A follow-up series of images was
obtained on July 30.07 with thin cloud present (with the new object
still at mag about 17.7).  SN 2001di is located at:
R.A. = 5h14m17s.57, Decl. = +72o20'41".0 (2000), which is 6" east
and 39" north of the nucleus of UGC 3259.  A CCD image (limiting
mag 19.5) taken by Armstrong on 2000 Nov. 3 shows nothing at this
position, and nothing is present on the following Palomar Sky
Survey images: 1953 Oct. 14, 1991 Dec. 7 (limiting blue mag 22.5),
1996 Oct. 2 (infrared).
IAUC 7673

Editor: Since this announcement appeared an independent
confirmatory image has been submitted to us by Gordon Rogers of
the TA Checking Group for which further details are awaited.
