AAVSO Alert Notice 814: HST observations of AB Aur this week
Abstract:
Further to Alert Notice 809, Dr. Lauren Biddle (University of Texas) informs us that a second set of HST observations of the bright (6.9-8.4V) young, accreting A0 Herbig Ae star, AB Aur has been scheduled.
Justification:
The science goals of this campaign would be best supported by a time-series with observational cadence that covers a range of timescales: high-cadence (hourly), medium cadence (weekly), and low-cadence (monthly).
