I am writing to propose that I receive some telescope time from BSM NM for a proprietary star that isn't a known variable of any type.
I have data from my schools telescope from when we were observing Exoplanet XO-2N b.
I request that I get a time series in V band measurements for a period of one month.
We would be using our schools telescope for this, but it is down for maintenance issues and it's proving difficult to get someone in to work on it due to COVID.
Thank you for your time and consideration.

The main concern I have with this proposal is the large amount of telescope time requested. If we had a rough ephemeris and could schedule the observations, I'd say go for it. But taking essentially half nights for 30 nights seems excessive. Maybe run this for 2-3 nights and see if the desired precision is reached? Can't they get a rough period from ASAS-SN or their data and TESS?
I realized this was a big ask and decided to get a rough period estimate even before you had requested them. Please see below:
We are thinking 28 days and no longer an exoplanet but likely a binary system.
TESS, ASAS-SN and our data all line up to roughly a 28 day period.
The next opportunity is going to be around December 11th. So if we could run from the 10th to the 13th, would that be acceptable?
Clarification: December 10th - 13th.
Approved for the nights of Dec 10-13. BSM_TX is recommended.
BSM TX is acceptable. Thank you for the quick turnaround!
Chris, please describe this more specifically: <<The requested cadence would be 25 to 50 observations spread evenly across every hour of the night as long as telescope time is available.>>
For the cadence, if I could get V band imagery of my target five times per hour at a 12 minute interval for the duration of each night, that would be preferable.
If a secondary cadence plan is required, please observe my target three times per hour at a 20 minute interval.
Committed to TX for 4 nights.
IMHO, this is a waste of resources to try to see an EB with depth of 0.02 mags! Best to wait until TESS takes some more images.
ASAS-SN data shows the star that is being observed to have greater variation than 0.02 mag.
The quoted magnitude is from non-proprietary data.
