The All Sky Automated Survey. The Catalog of the Short Period Variable Stars in the Selected Fields

Results of the first two month of observations using the All Sky Automated Survey prototype camera are presented. More than 45 000 stars in 24 Selected Fields covering 140 sq. degrees were monitored a few times a night resulting in the I-band catalog containing 10^7 individual measurements. Period search revealed 126 periodic variables brighter than 13 mag. Only 30 of them are known variables included in GCVS. The other 90 objects are newly detected variables - mainly eclipsing binaries (75%) and pulsating stars (17%). We estimate that completeness of the current catalogs of variable stars is smaller than 50% already for the stars brighter than 9 mag. The Catalog is accessible over the WWW: http://www.astrouw.edu.pl/$\sim$gp/asas/asas.html
