Note: HST will be observing Sz 76 again on August 8 from 11:27:38 through 18:56:12 UT. Please add this target to your observing queue if practical. Dr. Walter remarks that there will be no TESS data, so frequent (at least nightly) BVRI observations will be helpful for setting the context for the HST spectra. - Elizabeth O. Waagen, August 2, 2021
