Abstract
We made our CCD-observations of GSC
3950-00707 by using the telescope Celestron-14 of Vihorlat
Observatory and Astronomical Observatory on Kolonica
Saddle. The moments of minima were calculated by
using the symmetrical polynomial fit. We also analyzed
the observations from automated surveys ASAS-SN and
found 3 mean minima by using trigonometrical polynomial
fit. The analysis of our observations and data from
the surveys allows to conclude that it is the W UMa-type
variable and its published period value is not accurate. We
analyzed the O-C curve and corrected the elements.
