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 yamaoka@rc.kyushu-u.ac.jp
