Very rare outburst of the symbiotic variable AG Peg
Active Dates: June 23, 2015 – April 20, 2021
Abstract:
The symbiotic variable AG Peg is in outburst, the first one observed since its only known outburst, which occurred in 1860-1870. This campaign seeks to follow the outburst closely and learn what the system does during outburst. Observations in all bands and visual observations are strongly encouraged.
Justification:
AG Peg has a very interesting history with outbursts occurring approximately 140-145 years apart. Observations will help determine the behavior of the system during outburst.
