possible dwarf nova outburst asassn-22jz
Posted: Mon Aug 15, 2022 4:47 am
I took a spectrum of asassn-22jz, (also on TNS as AT 2022qwf ) which was listed as a possible CV .
It's just over 1 arcsecond from a mag 18 Gaia source included in a catalog of white dwarf,

I would love to extract the spectrum from the gaia archive but I can't manage to drive the python tools provided. It would be nice if a simple query - spectrum facility was included.
Elias Aydi of Ohio State university (asassn survey) has had a look and thinks it looks like a dwarf nova, but that there might be some pi cygni absorbtion on the blue side of Ha and Hb.
