Results of the first two months of observations using the All Sky Automated Survey prototype camera are presented. More than 45 000 stars in 24 Selected Fields covering 140 square degrees were monitored a few times per night resulting in the I-band catalog containing 107 individual measurements. Period search revealed 126 variable stars brighter than 13 mag with periods less than 20d. Only 30 of them are known variable stars included in the General Catalogue of Variable Stars. The other 90 objects are newly detected variable stars - 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/~gp/asas/asas.html
