\IBVSErem{
As a byproduct of the ROTSE1 CCD survey, a large number of new
variables have been discovered (Akerlof et al., 2000). In a series of papers, 
we report unfiltered CCD observations for some of the close binary systems 
(type EW) in the list of Akerlof et al. (2000). This installment 
contains information on four variables in the constellation Hercules. 
The four stars were observed with our CCD equipment during eight nights 
between JD\,2453121 and JD\,2453250. A total of 190 CCD frames were measured of 
GSC\,3510:5, 219 frames of GSC\,3097:1297, 215 frames of GSC\,3101:547 as 
well as 197 frames of GSC\,3106:1368. Figures 1 through 4 show our observations 
folded with the elements given in the Table of Ephemeris.  
These elements of variation are deduced from a linear fit to the normal 
minima from the ROTSE1 data and the timings of minimum derived from our data 
given in the table of Times of minima.}
