This is a HADS (High Amplitude Delta Scutii) star the I am observing monthly for an astronomer in Belgium who is doing a long term project on HADS stars. This one is multiple 2 min exposures and analysed with free software AstroImageJ.

Yes it's period is 3.20178 hours. It is the period that is being studied, I believe. There is the possibility of multiple periods.

Great work Dave, way beyond what most of us are doing.

Looking forward to your exoplanet talk at CPAC.
