On 2019 October 6 UT, we obtained the spectrum of this source with the Kast double spectrograph on the Shane 3 m telescope at Lick Observatory. Its spectrum shows a blue continuum and broad higher-order Balmer lines in absorption with weak emission cores, typical of dwarf novae, indicating that the observed event is a dwarf nova outburst.
