[vsnet-campaign-sn 534] SNe in NGC 4157 and IC 1129



Dear colleagues,

We submitted the following report of our spectroscopy of two
supernovae to CBAT.


SUPERNOVA IN NGC 4157
          K. Ayani, Bisei Astronomical Observatory (BAO); T. Hashimoto
and H. Yamaoka, Kyushu University, write:  "A preliminary reduction of
low-resolution spectrum (range 400-800 nm) of SN 2003? in NGC 4157,
obtained with BAO 1.01-m telescope on Jan. 12.8 UT, shows a prominent
H-alpha emission (FWHM about 10000 km/s) with a P-Cyg profile, which
suggests that it is a normal type-II supernova."


SUPERNOVA IN IC 1129
          K. Ayani, Bisei Astronomical Observatory (BAO); and H.
Yamaoka, Kyushu University, write: "A low-resolution spectrum (range
400-800 nm) of SN 2003? in IC 1129, obtained with BAO 1.01-m telescope
on Jan. 12.9 UT, indicates that it is a type-Ia supernova several days
before maximum light.  Adopting the NASA/IPAC Extragalactic Database
recession velocity of 6540 km/s, the expansion velocity deduced from
Si II (rest 635.5 nm) is about 12100 km/s."


Best ragards,
