Proposal	In support of Alert 750 and upcoming HST(8/26) and XMM-Newton measurements (Aug/Sept), propose nightly photometry of T CrB over next 6 weeks (prior to XMM-Newton schedule which is TBD) . Provide V,B(priority), I filter transformed photometry to AAVSO database. Observer: RBCA Data photometry: VPHOT Results: Upload to AAVSO database Target: T CrB Mag: 9 - 10.8 (prior to eruption in estimated 5 years) Filters + (exposure time): B(60sec), V(30 sec), I (20 sec) Number of exposures per filter: 16 Images to be stacked, photometry performed, transformed using comp + check star Start date: Aug 16th, 2021 End date: Sept 30th, 2021 Once HST, XMM- Newton observations are completed, project would continue at a 3 - 5 day cadence.
