continuing project headed by Howard Lanning (CSC/STScI). Several hundred faint
UV sources including many old novae, white dwarfs, cv's, Be shell stars, etc.
have been identified and presented in the literature and posted on the WWW. The
survey comprises over 100 Palomar (48-in.) Oschin Schmidt plates extending to a

( SAOimage )
(pronounced S-A-0-image) is a utility for displaying astronomical images which
runs under the X11 window environment. It was written by Mike Van Hilst at the
Smithsonian Astrophysical Observatory in 1990 and is now maintained by Doug
Mink. Image files can be read directly, or image data may be passed through a
named pipe (Unix) or a mailbox (VMS) from IRAF display tasks. SAOimage provides
a large selection of options for zooming, panning, scaling, coloring, pixel
readback, display blinking, and region specification. User interactions are
generally performed with the mouse.

The Swabian Observatory was founded in 1919. It is a non-profit-making
organisation. Since January 8th 1922 we operate an observatory located on a hill
in Stuttgart. The focal point of our astronomical work is the observation of
occultations of stars by the moon, the planets and their satellites, asteroids
and also mutual events. We measure the occultation timings with video and
photoelectric equipment up to 10.5 mag with an accuracy of +/-0.01s and up to
13.5 mag with an accuracy of +/-0.1s. We send our results to IOTA, EAON, BAA and
ILOC. Sometimes we make an excursion to observe grazing events with our
transportable telescopes, for example a Meade 2080HTC. Another main emphasis is
the observation of variable stars, mainly Mira type stars. Normally we measure
stars up to 15mag. At the moment we are beginning to observe variable stars with
the CCD camera ST-6. We send our results to AAVSO, AFOEV and BAV. [in German]

The conference on Science with the Next Generation Space Telescope (NGST) will
provide a forum for astronomers to discuss scientific goals and key problems
that this proposed observatory would address. NASA is currently studying several
concepts for the NGST, conceived as a successor to the Hubble Space Telescope.

The centres of the mosaics mirror the NVSS centres in the north. The resolution is 45" x 45"/sin(dec), and the rms noise limit varies from 1.3 to 2mJy/beam (lower toward the south celestial pole).
The survey began in March 1997 and will take eight years to complete. SUMSS is suported by funding from the Australian Research Council.
