  As part of the Transient UV Objects project, we have discovered a new
outburst (at the beginning of October 2020) 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.
