Dear VSNetters,
According to IAU Circular 6829, Supernova 1998S was detected in NGC
3877 on Mar. 3 UT by BAO Supernova Survey. It was about 15.2 mag
(unfiltered) on the discovery frame, and then rised to 13.5 mag (also
unfiltered) on Mar. 4.3 UT.
The location of SN 1998S is:
R.A. = 11h46m06s
Decl. = +47o29'.0 (2000.0)
which is 16" west and 46" south of the nucleus of the host galaxy. The
spectroscopy shows featureless continuum but probably with a broad
H-alpha emission, which indicates that this SN is of type-II in very
early phase.
The location of SN 1998S is embedded on the host galaxy. So the
photometry is rather difficult; but it is very challenging and the
results should be very useful. Following Observations are greatly
praisworthy.
Clear Skies,
