Andrea Reguitti (UNAB), Paolo Ochner (UniPd) report/s a classification of object: AT 2021pin

Type: CV

Remarks: The spectrum is similar to that of a Dwarf Nova in outburst, with a blue continuum and relatively broad (FWHM~2,500 km/s) Balmer lines in absorption. The Hbeta line is less prominent than Hgamma, and Halpha is not visible, probably filled by the emission from the accretion disk. Associated to a known SU UMa-Type Cataclysmic Variable V362 Lib, in outburst.
