Patrick Wiggins reported (already on 2022 April 30) that BC UMa was active in a CCD image that had been taken by him on my request (in the course of our CV monitoring programme) on April 30.430 UT. Unfortunately I checked my inbox only today.

The previous (super)outburst was also first detected by Wiggins (on 2020 August 16.228 UT, see vsnet-alert 24555).
Time-resolved photometry is required.
