There has apparently been a sudden rapid brightening of this star
as illustrated by the following visual estimates:
1992 Aug 30.886UT, 11.0 (W.Worraker, Didcot); 30.931, 11.2
(G.Poyner, Birmingham); 31.889, 10.3 (Worraker); Sept 1.817, 10.5
(P.Schmeer, Germany). Further estimates should be e-mailed to the
Editor as they are obtained in addition to the usual monthly
summaries to Tom Saville,
