Alert Notice 841: VY Scl coverage needed now for HST ToO observations (backup copy)

Notes:  VY Scl  is currently in its low state, and ongoing observations are requested. - Elizabeth O. Waagen, February 4, 2025

HST will not be able to observe VY Scl at this time, so the observations have been canceled. However, the data being obtained by you continue to be extremely valuable to the astronomers, and continuing coverage is requested until after VY Scl has returned to its bright state. Thank you!  -  Elizabeth O. Waagen, January 31, 2024
