SUPERNOVA 1999cl IN NGC 4501 = M88

IAUC 7815 announces the discovery of a bright SN in the nearby
galaxy M88:

     "M. Papenkova, A. V. Filippenko, and R. R. Treffers, University
of California at Berkeley, on behalf of the Lick Observatory
Supernova Search (cf. IAUC 6627, 7126), report their discovery of
an apparent supernova in an unfiltered image taken on May 29 UT
(mag 16.4) with the 0.8-m Katzman Automatic Imaging Telescope
(KAIT).  The object was confirmed in images taken on May 30 and 31
(mag 16.2 and 15.3, respectively).  Images from May 21 and 22 do
not show the object, to a limiting magnitude of 18.6.  The
supernova candidate is at R.A. = 12h31m55s.9, Decl. = +14o25'33"
(equinox 2000.0), which is about 46" west and 23" north of the
nucleus of NGC 4501". (IAUC 7815).

A type Ia SN in this galaxy might be expected to reach magnitude
14 and so extensive visual and CCD photometry is encouraged. At
mid-northern latitudes the Virgo/Coma area is well placed in the
southwest at the end of nautical twilight.
