Kivonat:

The Large Synoptic Survey Telescope (LSST) will be a large (6.7m effective 
aperture), wide-field (9.6 sq.deg. field-of-view) 
ground-based system designed to obtain deep imaging data in six broad bands 
(ugrizy, 320-1050 nm). Each sky position will 
be observed multiple times, with several hundred observations per band 
collected over the main survey area (20,000 sq.deg. 
with equatorial declination<+34.5 deg) during the anticipated 10 years of 
operations. The current observing strategy calls for 
about 10,000 sq.deg. of sky to be covered using pairs of 15-second exposures 
in two photometric bands spaced by about 
an hour within a night, and every three nights on average, with 5-sigma depth 
for point sources of r~24.5. The measured 
properties of newly discovered and known astrometric and photometric 
transients will be publicly reported within 60 sec 
after closing the shutter. I will summarize the main LSST science drivers, 
and will illustrate them using ongoing work based 
on SDSS and other data.
