Dear SN watchers,

Yasuo Sano has reported the bright magnitude (144C or 147C: depending on the reference stars)
for SN 2000C at Jan.18.5 UT It is quite brighter than typical SNeIa or SN 1998bw hyprenova model.
The followup observations and spectroscopical type determination (or whether it is SN or not)
are surely important for this object regretably left without published about its discovery.
Sincerely Yours, Hitoshi Yamaoka, Kyushu Univ., Japan

SN2000C bright! As suggested by Yamaoka and Sano, SN2000C is observed very bright!
