ASASSN-V J022007.17+610705.5 photometry campaign extended
Active Dates: Dec. 13, 2022 – March 31, 2023
Abstract:
VES 735 is the exciting star of the compact Galactic HII region KR 140. Hα spectra of the star show double-peaked emission indicative of material in a circumstellar disk.
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.
