Abstract:
Results of the first two months of observations using the All Sky
Survey prototype camera are presented. More than 45000 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
13mag with periods less than 20d. Only 30 of them are known variable
stars included in the General Catalogue of Variable Stars (II/214).
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 9mag.
The catalog is accessible over the WWW:

Note on ASAS:
The designation is based on J2000 position;
the "134460-3019.2" name was changed to "134500-3019.2"

Note on CrossId:
The cross-identification of ASAS J114736-6310.4 and 114736-6322.7
are flagged with an '*', they have been corrected at CDS (see the
"History" section below)
--------------------------------------------------------------------------------
History:
* 15-Jun-1998 Copied from http://www.astrouw.edu.pl/~gp/asas/asas.html
* 14-Jan-1999 Corrected the CKS identifications for 114736-6310.4 and
114736-6322.7, after discussion with Grzegorz Pojmanski:
"I misplaced "OtherID" for the two adjacent lines (in Table 3)"
and therefore the cross-identifications are:
ASAS J114736-6310.4 = CKS91 11451-6253
ASAS J114736-6322.7 = CKS91 11451-6305 = HD 309036
