Alert Notice 728: V510 Ori coverage needed for HST observations
Active Dates: Feb. 3, 2021 – Feb. 15, 2021
Abstract:
Further to AAVSO Alert Notice 725, Dr. Fred Walter (Stony Brook University) informs us that the T Tau star V510 Ori, one of the targets in his campaign on Northern T Tauri stars, will be re-observed with the Hubble Space Telescope on 12 February 2021 06:03 - 13:28 UT. Observers are requested to resume observations of this star and continue obtaining a few observations per night from now through February 15. The focus is on using standard broadband filters B, V, Ic; Rc and U are also useful. Visual observations are welcome.
Justification:
Re-observation with the Hubble Space Telescope necessitates observations through February 15.
