I have been looking for candidate stars for observation using the AAVSOnet facilities.

Looking at the Target Tool and selecting short period pulsators, beta Doradus shows up on the list.

It is in the SH about 62 degrees south.

It’s a DCEP with a period of 9.842675 and varies from 3.41V to 4.08 V.

Although it has over 9000 observations over the last 90 years, the vast majority of these (8718) are visual observations. There are about 200 obs in each of Johnson B and V and another 80 in Cousins R.

I would like to monitor this star for a period of about 6 months in BVRI using telescope BSM_South, at a cadence of once per night.

At some point, I would like to monitor the star more intensively (several times per night) over a 10-day period to get a better idea of what the light curve is doing, during the rise to maximum.

I meant to ask that my images be sent to VPhot. Thank you.
