In response to the message on E261, P.Schmeer, Germany e-mails
that he observed it on Feb 17.13UT at magnitude 7.9v.

NSV 01098
P.Schmeer also e-mails results on this star, rediscovered by
M.Collins, which he has reduced to the latest TA sequence:
Jan 14.034UT, 9.3; 24.877,9.5; 26.026,9.5; Feb 14.973,9.6;
17.091, 9.6 (0.203-m SC).

SUPERNOVA 1989B IN M66
We have so far received 48 results on this object and time and
space prevent giving full details at this stage. However it
appears that the supernova reached 12.0 visual at maximum but the
date was ill-defined, probably around Feb 10-12. It is noticeable
that photographic results on a variety of films record the
supernova about 0.2 magnitudes brighter than the visual results on
the same dates. This was also the case with SN 1980K in NGC 6946.
It is also apparent that SN 1989B is already the best observed
extragalactic supernova in the northern sky since SN 1980K for
which in excess of 200 results were obtained. It is very important
that we continue intensive coverage and that photographers
also take regular shots, especially as the supernova fades below
the limit of visual observers. When e-mailing results please quote
the date, time, FULL estimate (eg A(1(v(1)B), sequence used,
magnitude, class, instrument, and for photos the film and filter.
