[vsnet-campaign-sn 609] possible SN in UGC 9638

Dear SN watchers,

  IAUC 8121 informed the discovery of apparent supernova (mag 16.2) in
UGC 9638.  The position of the object is reported as 14:58:04.92,
+58:52:49.9, which is about 38" west and 32" north of the center of an
irregular galaxy UGC 9638.  But IAUC also noted that there is an
USNO-A2.0 star about 3" from this position.

  I quickly see the catalogs.
USNO-A2.0  14 58 04.548 +58 52 49.19 r=18.2  b=19.6 epoch=1955.205
GSC-2.2    14 58 04.504 +58 52 49.27 r=18.35 b=-    epoch=1995.155

  Unfortunately 2MASS doesn't contain this star.

  If the position difference between these catalogs is reflection of
the proper motion, it seems to consistent that this USNO-A2.0 star is
positionally coincident with the reported object.

  Because I am out of office in some days, I can't study further.
Please give further comments whoever possible.

Sincerely Yours,
Hitoshi Yamaoka, Kyushu Univ., Japan
