A photometric survey of three Southern target fields with BEST II yielded the detection of 2,406 previously unknown variable stars and an additional 617 stars with suspected variability .
This study presents a catalog including their coordinates , magnitudes , light curves , ephemerides , amplitudes , and type of variability .
In addition , the variability of 17 known objects is confirmed , thus validating the results .
The catalog contains a number of known and new variables that are of interest for further astrophysical investigations , in order to , e.g. , search for additional bodies in eclipsing binary systems , or to test stellar interior models .

Altogether , 209,070 stars were monitored with BEST II during a total of 128 nights in 2009/2010 .
The overall variability fraction of 1.2–1.5 % in these target fields is well comparable to similar ground-based photometric surveys .
Within the main magnitude range of R \in \left [ 11 , 17 \right ] , we identify 0.67 ( 3 ) % of all stars to be eclipsing binaries , which indicates a completeness of about one third for this particular type in comparison to space surveys .
