of our CV monitoring programme).

Only two previous outbursts were recorded:
In late August and early September 1927 (C. Hoffmeister)
and on 11-29 August 1966 (H. Gessner), see IBVS 5441 at

Time-resolved photometry is urgently required.
Spectroscopy, multiband photometry, and precise
astrometry are also encouraged.

Clear skies,
