[vsnet-campaign-sn 450] SN observations from IAUC 7933

SN2002dx  20011119.2  <195:C  KAI
SN2002dx  20020708.5   188:C  KAI
SN2002dx  20020709.5   189:C  KAI

# The host galaxy of SN 2002dx is UGC 12861, a faint spiral (Sab)
# galaxy.  The expected maximum for typical SN Ia is mag about 16.7,
# but it seems not to be of this type in the early phase.

SN2002dy  20011102.2  <195:C  KAI
SN2002dy  20020708.5   170:C  KAI
SN2002dy  20020709.5   170:C  KAI

# MCG -01-59-24, the host galaxy of SN 2002dy, is a distant spiral
# (SABc) galaxy, which makes a pair with MCG -01-59-25 (1'.3 NE).  The
# CfA spectrum taken on July 10.47 UT revealed that it is of type II,
# and the narrowness (FWHM = 3100 km/s) of the hydrogen emission
# suggest that it would be of type IIn.  The discovery magnitude is as
# bright as the expected maximum for typical SN Ia, which is
# consistent with bright SN IIn nature.  Such bright SN IIn, which
# somebody call as "type IIn hypernovae", are thought to be related
# with the gamma-ray bursts (GRBs), but no GRB detection in this field
# was reported in these three months.
