Dear Colleagues,
Since compiling the original database of visual observations for
'The Astronomer' and BAA, numerous other results have been
received and the list currently being updated.

Amongst these is a photograph by Oliver Schneider taken on
1993 Mar 26/27:
Start Mar 26 23.30UT
End   Mar 27 00.15UT

Mean 1993 Mar 26.995UT

0.21-m reflector. Film: Kodak 2415 hypered.
From: Bielefeld, Germany

It does not appear that the supernova is visible although there
may just be something at the extreme limit of the photograph.

However I can see a star which appears to correspond to the mag
17 object referred to on IAUC 5737 by W. van Driel, some 50"
north of Star C.

Does anyone have an accurate magnitude for the magnitude 17 star
and any other stars (mag 16-20) within about 20 arc minutes of the
supernova please?

At present the result is:
1993 Mar 26.995UT, [17
