TW Hya being observed by HST now - observations needed
Abstract:
The AAVSO is calling for observations of the young stellar object (YSO) TW Hya, synchronized with HST observations to piece together the behavior of the star.
Justification:
It is important to get single BVRI sequences each night, but longer sets of data would be useful if they can be obtained simultaneously with the HST observations. Moreover, having a positive V observation 24 hours before the scheduled HST time is extremely important.
