D. Nogami and S. Masuda at Ouda Station relay that V725 Aql (see vsnet-
alert messages concerning the new identification) has entered a rapid
decay phase. They provide following preliminary magnitude estimates.
mid-UT V-C S.D. N band approx. V-mag

The present observations seem to establish the dwarf-nova nature of
the object in question. The large outburst amplitude (~6 mag) and the
long outburst duration may indicate that V725 Aql is a 'TOAD' (tremendous
outburst amplitude dwarf nova). We welcome follow-up observations and
future monitor by visual observers.
