Alert Notice 760: GM Aur and V1204 Tau to be observed with HST
Abstract:
Observations of GM Aur are complete. The HST observations of V1204 Tau did not take place and will be rescheduled for sometime over the next three months.
Justification:
AAVSO observers' assistance is requested in monitoring these pre-main sequence targets before, during, and after the HST observations. A positive V observation is crucial 24 hours before the scheduled start time to allow the HST team to make a go/nogo decision.
