A photometric minimum feature was confirmed to be periodic and comparison to a previous event indicated that the period to within our error was 2022.6±1.0 d. Using the E-region standard star system, the apparent V magnitudes determined for the local comparison stars were HD 303308 8.14±0.02, HD 93205 7.77±0.03, and HD 93162 8.22±0.05. The latter star was found to be dimmer than previously reported.
