Possible brightening of AG Dra
The symbiotic variable AG Dra seems to show a tendency to rise, which may
be an indication of the next activity cycle following the 1996 July one.
Luthardt (in "Flares and Flashes", p.262) suggested the existence of an
optical periodicity of P=356 d, in addition to the U-band periodicity of
554 d (Meinunger, IBVS 1611).
