Query: Observations and light curve solutions of the eclipsing stars CSS
  J075205.6+381909 and NSVS 691550   The paper presents observations and light curve solutions of the eclipsing
stars CSS J075205.6+381909 and NSVS 691550. As a result their initial epochs
were determined. The target periods turned out almost equal to the previous
values. We found that NSVS 691550 is overcontact system whose components are
close in temperature while CSS J075205.6+381909 has almost contact
configuration and temperature difference of its components is around 2000 K.
Both targets undergo partial eclipses. Their stellar components seem to obey
the relations mass-temperature of MS stars.
