1 de Miguel , Enrique Two primary eclipses are seen which, in addition to the one reported by C. Littlefield allows determination of the period of this EA variaible. The secondary eclipse is very shallow, with an approximate depth of 0.03 mag.
2 Littlefield, Colin Only one eclipse was seen in 17 time series. A complete list of these time series, including their start and end times, is available in the referenced paper. No eclipses are present in SuperWASP data. Neither ASAS nor NSVS has photometry of this star.
