Dear friends:
according to Stefano's observation time (Aug 26.9 UT) ngc1961 was fairly
low on the horizon (<30deg) with an atmospheric extinction of 0.4 mag.
Should sn1998eb have reached its maximum peak in the 15-15.5 range, it
would have been very difficult to be spotted visually by an instrument with
a limiting mag of 15.8, yet due to the fact this sn is located in a bright
arm of the host galaxy.
A CCD unfiltered image which I have taken at CAM Observatory, Promiod,
Italy on Sep 24.16 UT shows sn1998eb @ m=18.1 (see attached Jpeg image).
This shows that sn1998eb would have not been brighter than 16 mag at its
maximum peak.
Clear skies!
Dr. Giuseppe A. Sala
