T LEONIS
Further to the appeal on E-159, P.Schmeer, J.Isles and the editor
all agree that the sequence adopted from the AAVSO is seriously in
error with some comparisons more than 1.5 magnitudes adrift.
Using photographs by D.Buczynski for transfer from RZ Leonis and
visual estimates by Isles, a new sequence has been derived and new
'B' and 'C' charts are now available from T Leo under revision
880619.
Based on the revised comparison star magnitudes the recent maximum
may have been as faint as 11.0. It is interesting to note that
maxima derived by W.Wenzel in MVS 10(3),1984 have the star
reaching 11.0-11.5pg 1945-1983 and presumably the colour index is
small.

ELECTRONICS IN ASTRONOMY
We have received a request for help in preparing a lecture on the
above subject from Peter Holmes of Knaresborough. If anyone could
help in this subject please e-mail the Editor.

COMPUNET
The Astronomer now has its own bulletin board on COMPUNET. Goto
page 372694 for further details. Messages can be sent to GMH4 but
urgent ones should be sent on MICROLINK as COMPUNET may only be
checked weekly. If anyone is already on COMPUNET please send me
your mailbox number.
