COMET P/2001 M1 (HELIN)
M. Busch, A. Seib, F. Hormuth, and R. Stoss, Starkenburg-
Sternwarte, Heppenheim; and A. Gnadig and A. Doppler, Archenhold-
Sternwarte, Berlin, report the recovery of P/1987 Q3 (= 1987w =
1987 XVII) on CCD images taken by Busch, Seib, and Hormuth with the
EOCA 1.52-m reflector at Calar Alto, with the astrometry given
below (measurements by Stoss, Gnadig, and Doppler).  The indicated
correction to the prediction by B. G. Marsden on MPC 31664
(ephemeris on MPC 42160) is Delta(T) = -1.0 day.

SUPERNOVA 2001cp IN UGC 10738
M. Modjaz and W. D. Li, University of California at Berkeley,
report the discovery by LOTOSS of an apparent supernova in
unfiltered images taken with the Katzman Automatic Imaging
Telescope (KAIT) on June 19.3 (mag about 16.5) and 20.3 UT (mag
about 16.3).  SN 2001cp is located at R.A. = 17h11m02s.58,
Decl. = +5 50'26".8 (2000), which is 49".1 west and 40".0 south of
the nucleus of UGC 10738.

BC UMA (Q2001/228)
Mike Simonsen, USA reports his detection of an outburst of BC UMa
on 2001 June 25.170 at 13.7v using a 0.25-m Schmidt-Cassegrain
telescope. This was confirmed by M.Reszelski, Poland on
June 25.898UT at 13.2v (0.41-m reflector). Gary Poyner, Birmingham
reports the object was not seen on June 24.972UT to a limit of 14.0.

Mike Simonsen subsequently provided follow-up estimates:
2001 June 26.184UT, 13.1; 27.156, 13.1.
