Abstract: | A peculiar nova-like MV Lyr was investigated. The CCD-observations of MV Lyr were continued in Crimea during the outbursts
and quiescent states. Last year its behavior became non-typical for “anti-dwarf novae”. The length of its first deep minimum
was 10 years. A modern state is characterized by very strong outbursts and very often changes of the stages. The periods 0.
d
128 and 0.

136 were obtained for 1998 and 1999 years accordingly. Possibly, a relation between the photometric period and the brightness
exists. |
