SN 2002an
As IAUC 7805 reported, Y. Sano discovered a supernova SN 2002an in the
nearby galaxy on Jan. 22.52 when its unfiltered red magnitude was 16.04.
The position of this new object is about 38" east and 7" south of the
nucleus of a face-on open spiral galaxy NGC 2575. The expected maximum
for typical SN Ia in this galaxy is mag about 15.4. Kushida noted that
it became slightly brighter on Jan. 24.729, and nothing was visible on
Jan. 6. (vsnet-campaign-sn
321). IAUC 7808 informed that SN 2002an was not detected on Jan. 17.54.
Thus, it should be discovered during an early phase (vsnet-campaign-sn
324). According to IAUC 7818, the spectrum taken on Jan. 31 at Wise
Observatory showed a blue continuum with narrow H-alpha emission, resembled
that of SN IIn 1998S around maximum. The brightest reported magnitude
of SN 2002an is 155CR on Jan. 25, which is near to the expected maximum
of SN Ia (vsnet-campaign-sn
337, 340).
The object then started fading (vsnet-campaign-sn
347, 350,
354,
359,
362).
