Abstract:
We present new photometric data for an EW-type binary star – MM Dra. Light curve data in B and R colors for a total of 37 hours of observation have been analyzed. We obtained a new period of the binary – 0.26548 (0.00001) days, slightly larger than previous estimates, but broadly consistent with the previously reported minima epochs. The presence of O’Connel effect in the light curve is noted.
