SN 2002bu
99 SN 2002bu was discovered at 15.5mag on Mar. 28.26 UT at Puckett
Observatory. The position of the SN is about 73" east and 98" north of
the center of the somewhat irregular-shaped galaxy NGC 4242. NGC 4242
is a member of a nearby group of galaxy called "Canes Venatici II cloud",
whose mean redshift is about 750 km/s. The expected maximum for the typical
SN Ia is mag about 11.7, and even if it is of type-II, it can become brighter
than mag 14 (vsnet-campaign-sn
387). K. Ayani, T. Kawabata, and H. Yamaoka performed spectroscopy
and reported that it showed a flat continuum with strong and narrow Balmar
emission lines, which indicates that it is of type IIn (vsnet-campaign-sn
391). The object recorded about 15mag (vsnet-campaign-sn
392, 395,
403).
