Query: Evidence for High Eccentricity and Apsidal Motion in the Detached
  Eclipsing Binary GSC 04052-01378   We observed the recently discovered eccentric eclipsing binary GSC
04052-01378 in order to improve the light curve parameters and to find further
evidence of its probable high eccentricity and of apsidal motion. Furthermore,
we propose a basic stellar model that fits very well the observations of our
dataset and where the eccentricity is found to be e = 0.538(6), which
corresponds to an high value among this group of binaries.
