Anticipated primary eclipse of b Persei in January 2020
Active Dates: Jan. 5, 2020 – Feb. 2, 2020
Abstract:
The bright (4.6 V) triple-star, eclipsing system b Persei has been the subject of several AAVSO campaigns. The current campaign requests high time-resolved observations of the bright star b Persei during the upcoming predicted primary eclipse, or transit, of the third star across the system.
Justification:
The recent campaigns by AAVSO observers have revealed significant light curve dips and Radial velocity observations indicate this event is another opportunity to gather critical data on the b Persei system.
