Schwäbischen Sternwarte

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]

SUMSS is a deep radio survey of the entire sky south of declination -30 degrees, made using the Molonglo Observatory Synthesis Telescope, operating at 843MHz and recording right-circular polarization.
SUMSS matches (approximately) the resolution and depth of the NRAO-VLA Sky Survey (NVSS). The principal data products are mosaics which cover a 4x4 degree square on the sky. 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.
The primary reference for a description of the survey is:
