Date SubmittedFeb. 2, 2021

Name: Peter Bealo
Code: BPEC
Observation Use: Obtain a deep snapshot to look for close companions to target and comp stars
Use of Data: Submit to AAVSO Database after VPhot analysis
Target Star: ASASSN-V J170615.23-322944.7 in SCO
Magnitude Range: 12. – 13.5 mag

Observation Cadence: Do once
Filters Required: V, I
Number of Exposures per Run: 3X per filter

See proposal 185.
I am requesting just 2 or 3 images in V and I from OC61 or TMO61, per Dirk Terrell's suggestion, to obtain a deep snapshot to look for close companions, to help in understanding the amplitude of any variation in the target.

Proposal 185 is for monitoring over time. This proposal is just a "one and done" effort.
