First Ultraviolet Outburst Detected from ASASSN-18eh Strengthens Its Interpretation as a Cataclysmic Variable.

Abstract (from CDS):

As part of the Transient UV Objects project, we have discovered a new outburst (at the beginning of 2020 October) of the candidate cataclysmic variable (CV) ASASSN-18eh using the UV/Optical Telescope aboard the Neil Gehrels Swift Observatory. During the outburst its brightness increased by about 6 mag in UV compared to its brightness in the quiescent state. The properties of this outburst are consistent with it being a dwarf nova, strongly supporting the CV nature of ASASSN-18eh.
