This system was observed as a part of our student/professional collaborative studies of interacting binaries from data taken from the national undergraduate research observatory (NURO). The observations were taken by RGS and NB. Reduction and analyses were jointly completed by RGS and AJ. The present 2010 UBVRI light curves were taken with the Lowell 0.81-m reflector in Flagstaff on May 10 and May 11 with CRYOTIGER cooled (−100°C) 2048X2048 NASACAM and standard UBVRI Besell filters. The individual observations included 216 in the U-filter, 230 in B, 232 in V, 243 in R, and 239 in I. The standard error of a single observation was 1% in U, V, and R and I an 1.2% in B (Table

Observations taken over some 5000 orbits (5.3 years) seem to show a constant period. A quadratic ephemeris was calculated, but the negative quadratic term was not significant. Further observations are needed to determine any trends that indicate changes in period.
Observations of over a dozen Landolt standard stars along with the variable, comparison, and check stars throughout the evening of May 11 allowed us to calculate principal and transformation coefficients in BVR and I. Comparing these to Kron-Cousins calibrations, we found the results given in Table
Standard magnitudes of the variable, comparison and check stars.
