Dear SN watchers,
Some additional informations about SN 1999em:
[Spectroscopy and Astrometry]
IAUC 7296 noticed that it is of type II in an early phase. SN seems
to be obscured some. The position of SN is also reported: the offset
from the host nucleus is 15".4 west and 17".0 south, as being
remarked.
[Comparison Stars]
In my table on [vsnet-alert 3640], the GSC-ID of one star is
incorrect. Thank you Dr. Llapasset for pointing it out.
>GSC0473901361 29s.981 48'07".42 29"E202"N 13.75
should read
GSC0473900125 29s.981 48'07".42 29"E202"N 13.75
Other useful informations are given by Prof. Skiff and Dr. Kato;
