ORFEUS MISSION
Gary Poyner e-mails:
"Astronomers at the Harvard-Smithsonian Center for Astrophysics,
and Lawrence Livermore National Laboratories, California  will be
observing some dwarf novae and magnetic novalike variable stars
during the forthcoming ORFEUS  (Orbiting and Retrievable Far and
Extreme Ultraviolet Spectrograph) mission, and have asked for
our assistance.
The missions primary goal is to observe stars that emit most of
their light in the ultraviolet band of the electromagnetic
spectrum.  The mission is expected to last for 5 days.

Below is a list of their primary observing targets during the
mission.

Star         Range
RX And      10.3-14.5
VW Hyi       8.4-14.4
Z Cam       10.2-13.8
AM Her      12.4-15.3
SS Cyg       8.1-12.4
RU Peg       9.4-13.1

Please monitor these stars between now and the end of the mission
or the end of July (which ever is later), and telephone or e-mail
your observations of outbursts of dwarf novae (or activity in the
case AM Her) to Gary Poyner on:
Tel Int:+44 21 350 4312; UK 021-350-4312
BHVAD
UK.AC.Bham.SR.Star
The telephone number is available all night for the reporting of
such outbursts.

In addition to this list, if any other of the brighter dwarf novae
reach  magnitude 12 or above, please report these also.

V344 LYRAE
Gary Poyner, Birmingham e-mails his detection of a faint outburst
of this UG star which has been confirmed by John Day, Leicester:
1993 July 7.963UT, [14.8 (Poyner); 9.946, 15.1 (Poyner); 9.981,
15.1 (Day); 10.961, 15.3 (Poyner).

NO SUPERNOVAE 1993U AND 1993V
A. V. Filippenko, T. Matheson, and L. C. Ho, University of
California at Berkeley, report that fully calibrated CCD spectra
(range 320-1000 nm) obtained on June 28 UT with the Shane 3-m
reflector at Lick Observatory reveal that SNe 1993U and 1993V (cf.
IAUC 5818) are actually quasi-stellar objects (QSO).
IAUC 5829

UK NOVA/SUPERNOVA PATROL
Effective today, observations of recurrent objects (as listed on
that part of the programme) should be sent to Gary Poyner whereas
novae, supernovae and suspected variables should be reported to the
main Editor. Separate newly designed forms for the monthly reports
are available on e-mail request.
