Abstract:
Results of the first two years of observations using the All Sky
Automated Survey prototype camera are presented. More than 140000
stars in 50 Selected Fields covering 300 square degrees were monitored
each clear night in the I-band resulting in the ASAS Photometric
I-band Catalog containing over 5*107 individual measurements.
Nightly monitoring of over 100 standard stars confirms that most of
our data remains within σI=0.03mag of the standard I system.
Search for the stars varying on the time scales longer than a day
revealed about 3800 variable stars (mostly irregular, pulsating and
binaries) brighter than 13mag. Only 630 of them are known or suspected
variables included in the GCVS (Kholopov 1985, Cat. II/214). Among
the stars brighter than I∼7.5 (which are saturated on our frames) we
have found about 50 variables (12 are in the GCVS, 6 others in the
Hipparcos catalog (Cat. I/239). Because of the large volume of data
we present here only selected tables and light curves, but the
complete ASAS Catalog of Variable Stars (currently divided into
Periodic and Miscellaneous sections) and all photometric data are
available on the Internet http://www.astrouw.edu.pl/~gp/asas/asas.html

* 11-Sep-2005: Copied at http://archive.princeton.edu/~asas/
* 28-Nov-2006: Apparently incorrect Vname in lcmisc.dat corrected:
-- ASAS J190333-2317.8 is V1236 Sgr (not V1236 Oph)
-- ASAS J170543-2151.4 and J170543-2209.2 were both associated to
V1343 Oph which is too far away.
