I need some observations on this star in V filter. The star needs to be observed for 2 variability cycles. The VSX period is 0.0749808 d. The observations will be used to calculate the star's temperature during the variability cycle and make a temperature vs phase graph. The research's goal is to further understand how the amplitude, period and temperature change are related in DSCT stars. I hope the observations get approved. The range is given in Rotse-1 band.

From Arne:
The field is uncrowded, and shouldn't be a problem with the BSMs. Since DSCT stars are quite blue, BVI would be possible. That said, you would like a cadence of about 1 minute for good period resolution. I'd probably do V=60 and I=60 exposures, which give about 50 datasets per cycle, and then do a single night time series of at least 4 hours on one BSM for the observer.

Thank you. This is perfect! When will the data be ready?
