[vsnet-alert 24773] Re: [vsnet-campaign-dn 14859] ASASSN-18rg possible outburst (AM CVn star)

[反保雄介]

Kyoto Univ. Obs. and Maeda-san observed ASASSN-18rg on 5th and 6th Oct.,
however it was under their limit magnitude.
So the detection by ZTF Lasair is likely a false alert.

YYYYMMDD(UT)   mag  observer

20201006.4227 <15.2CV Mdy
