SUPERNOVA 2007cm IN NGC 4644
     W. Kloehr, Schweinfurt, Germany, reports the discovery of an apparent
supernova (mag about 16.1) on six unfiltered CCD images taken on May 24.024
UT with a 20-cm Meade DSI-Pro II Schmidt-Cassegrain telescope.  The new
object is located at R.A. = 12h42m45s.18, Decl. = +55o08'57".1 (equinox
2000.0), which is 21".5 east and 13".5 north of the center of NGC 4644.  A
Palomar Sky Survey II image shows nothing at this position.  Kloehr
provides the following additional unfiltered CCD magnitudes for 2007cm:
Mar. 27, [17.5 (Kloehr); May 16.22, [19.0 (W. Li, University of California
at Berkeley, KAIT); 24.21, 17.5 (Li); 24.398, 16.0 (M. Nicholson, Mayhill,
NM); 24.854, 16.2 (A. Dimai and M. Migliardi, Cortina d'Ampezzo, Italy).
