A number of observers in the UK have returned negative results tonight, so unfortunately this looks like a false alarm.
Thanks to everyone who responded so quickly.

I will try to observe this target tonight from my backyard in Belgium.

Jose Ripero has reported (on vsobs share, May 7) that the UGWZ star PR Her is in outburst.
HERPR 20220507.9597 13.6 OJR Active
Since its discovery in 1951 by Hoffmeister (from a photographic plate) the only major outburst to have been covered well occurred in November 2011. Since then there have been several faint detections (below mag 15) reported to the AAVSO database (the last one being in June 2020 at 16.7V by Roger Pickard). The quiescent magnitude is around 21.0.
Confirmation is urgently requested.
