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 https://konkoly.hu/pub/ibvs/5401/5441.pdf
Time-resolved photometry is urgently required. Spectroscopy, multiband photometry, and precise astrometry are also encouraged.
Clear skies,
Patrick
