[vsnet-alert 5224] MV Lyr rapid brightening

MV Lyr rapid brightening

   The VY Scl-type novalike variable MV Lyr has rapidly brightened.
The present brightening may have been dwarf nova-type, as judged from
the atypical speed of rise.  Time-series photometry is strongly encouraged
to clarify the present state (are superhumps visible?)
