Proposal

I would like to observe GrAGVar013 and confirm its variability with the entry on the VSX (there was only one source for the period and I would like to contribute to confirming the period). This observation will be used for both research and educational uses.

I am requesting exposures of 3 seconds each

Please run around 5 images for the B filter, and as many as possible for the V filter.

It would be of great help if the images could be collected before May 12, thanks.

You have said nothing about its known period. One small set of images are not going to be useful for a period analysis!

Its known period is 71.7 minutes (0.04979). I want to use small amounts of data to piece together to fold a period. I do not need much data but having data over many different nights would be of much help, thanks!

Ideal end date changed to May 23.

The amplitude of this object is 3 millimag, a tough target to do from the ground. What makes this target worthy of such hard work?

The TAC has decided that a 3 mmag amplitude is too small to achieve with AAVSOnet and thus declines the proposal.
