J. L. Prieto (UDP), K. Boutsia (LCO), T. Holoien (Carnegie) report/s a classification of object: AT 2017gwx

Type: CV

Remarks: We obtained an optical spectrum of ASASSN-17my/AT2017gwx on UT 2017 Sep. 27.1 with IMACS (range 4100-9200 Angs.) mounted on the Magellan Baade 6.5m telescope at LCO. The spectrum shows a blue continuum with H-alpha (double-peaked), He I 5875 and He II 4686 in emission, and H-beta and H-gamma in absorption, all at z=0. This is consistent with a CV in outburst.
