Lina Tomasella report/s a classification of object: AT 2016cxa

Type: CV

Remarks: The spectrum shows a blue continuum with narrow Halpha, Hbeta and Hgamma in emission at the rest wavelength. The object is therefore not a supernova but most likely a cataclismic variable (CV). The Balmer decrement from the emission components, with the presence of a fairly strong Halpha and higher members of the series showing progressively stronger absorptions, confirms the classification as a dwarf nova. Also the He I emission at 587.6 nm is clearly visible.

The following Classification spectrum was provided:
