Abstract: ER UMa is a well known SU UMa-type dwarf nova with a number of outstanding properties. It is the prototype of a small group of dwarf novae with a high frequency of superoutbursts and a short orbital period. Our multicolor BVRcIc investigation of ER UMa carried out at the Crimean astrophysical observatory in 2020 showed that in some occasions ER UMa may be a "bridge" between the subclasses of ER UMa-type stars and nova-like ones.
