Proposal

In support of Alert 836 "AAVSO and SNEWS partner in campaign to monitor bright supernova progenitors", perform V and I band photometry on a subset of target stars listed as part of this campaign. I've chosen stars that have not been regularly observed in order to increase coverage of the target list.

Observer: RBCA
Data photometry: VPHOT
Results: Upload to AAVSO database
Filters + (exposure time): V(20 sec), I (10 sec)
Number of exposures per filter: 3
Duration of project: Ongoing
Cadence: Once per week
Targets: (Total=10) subset of the SNEWS campaign target list of 192 starts

Please have a look at https://www.aavso.org/snews-campaign-forum and coordinate with other observers on targets, noting the BSM field limitations.

Per my note on the snews campaign forum dated Oct 17th: "Coordinating use of the BSM AAVSOnet for the SNEWS Campaign", I've set up a google sheet with a column for observer sign up. Recommendations are made for selecting targets using the BSM . I've signed up for these 10 stars and there are two other observers that have signed up. The link to the google sheet is on the SNEWS forum.

My apologies. I didn't make the connection that you were the creator of the spreadsheet. Thank you for doing that. I'll go ahead an mark this one approved.
