Proposal #313

Monitor the faint stars in the Super Nova Candidate list

This proposal is complementary to Proposal #242. That proposal uses AAVSONet Bright Star Monitor stations to monitor stars in the AAVSO SNEWS Campaign (https://www.aavso.org/snews-campaign). This is a list developed in a collaboration with SNEWS (Super Nova Early Warning System. see https://snews2.org/ ) It was created in December 2021 with an emphasis on brighter stars and thus Proposal #242 was assigned to AAVSONet BSM stations. This has been quite successful, providing almost 3000 observations and playing a major role in reducing the number of stars with zero observations in AID from 57 at the start of the campaign to 6 (as of 01/15/2023). The present proposal looks to extend the monitoring to the FSM stations. There are three main goals:

1) monitor the stars in the SNEWS Campaign list with V magnitude > 10

2) support the efforts of the SNEWS team to extend the list of candidate stars by monitoring potential additions to the list with V magnitude > 10. For this pilot effort, we choose stars on the SNEWS extended list that are already in VSX with an AUID.

3) support the efforts of AAVSO to bring full support for data with Sloan filters to the AAVSO software and databases by providing an ongoing source of data, analysis, and feedback for using Sloan filter data in AAVSO software.

Details would be as in Proposal #242; priorities set to just above survey level, images routed to Daniel Zaharevitz (ZDAB), plan sent to two FSM's one north, one south. The goal for initial cadence is 10 days. The multi filter photometry is requested, most likely B V SG SR SI, but whatever is available on the assigned telescope.
