Confirmation of probable new WZ Sge star AT2019vww
Posted: Thu Dec 12, 2019 11:55 pm
AT2019vww was discovered by the amateur Italian Supernova Search Project. 2019-11-30 It was considered a possible supernova as it was close to galaxy IC11775 . However it was confirmed from the redshift to be a galactic source, a probable CV using my ALPY 200 2019-12-01
The confirming spectrum taken at ~mag 15.5 can be seen here

and an Atel confirming the discovery has now been issued

Nothing is visible in deep images so the outburst must be >mag 7 so probably a WZ Sge type dwarf nova, though perhaps a classical nova cannot be ruled out as it cannot be distinguished from the width of the H alpha line in this low resolution spectrum
