Dear SN watchers,

  M. Schwartz, OR, has made his 15th SN discovery! (is this number
correct? > Mike)  According to IAUC 7178, the new object was found on
May 22.27, when the magnitude was about 15.9.  The location is R.A. 
= 13h33m29s.71, Decl. = +33o03'22".9 (2000.0), which is about 8" east
and 50" north from the core of the host galaxy UGC 8539.  As B. Skiff
noted, this galaxy seems somewhat active.  There is two foreground
stars (mag about 16 for both) 65"E34"N and 83"E36"N.  Also there is
another galaxy PGC 47720 = KUG 1330+333 about 5' northwest from UGC
8539. 

  These galaxis would be members of Coma (super)cluster, and the
recession velocity of UGC 8539 is consistent of this hypothesis.
However, the reported magnitude of SN 1999cf is quite brighter than
the normal SNeIa in Coma.  The followup photometry and spectroscopy is
a matter of great concern.

Sincerely Yours,
Hitoshi Yamaoka, Kyushu Univ., Japan
