ASASSN-V J022007.17+610705.5 photometry requested in support of spectroscopy observations
Active Dates: Oct. 13, 2022 – April 30, 2023
Abstract:
Drs. Brandon Marshall and Charles Kerton request AAVSO observers' assistance in monitoring the unique variable ASASSN-V J022007.17+610705.5 (Cas) = VES 735 in support of spectroscopy observations being obtained at the Dominion Astrophysical Observatory in October, November, and December.
Justification:
The goal of the DAO campaign is to determine if the emission has returned to its pre-outburst state or if the strong emission is still ongoing. The AAVSO observing campaign observations will allow us to see if there is a relationship between the star’s Hα brightness and the star’s V-band magnitude.
