[Hitoshi YAMAOKA <yamaoka@rc.kyushu-u.ac.jp>]

Dear SN watchers,

  We have submitted an article below to CBAT.

SUPERNOVA 2002bu IN NGC 4242
     K. Ayani and T. Kawabata, Bisei Astronomical Observatory (BAO);
and H. Yamaoka, Kyushu University, report:  "We obtained a
low-resolution spectrum (range 400-700 nm; resolution 0.7 nm) of SN
2001bu (IAUC 7863) with the BAO 1.01-m reflector on Mar. 31.66 UT.  
It shows a flat continuum with strong and narrow (FWHM about 1100
km/s) Balmar emission lines, which indicates that it is of type IIn.
The redshifts of emission lines are about 600 km/s, which is consistent
with that of NGC 4242.
