[vsnet-campaign 417] V725 Aql outburst
V725 Aql outburst
As reported by M. Simonsen in [vsnet-obs 29019] and by G. Poyner in
[vsnet-outburst 373], and confirmed by C. Jones in [vsnet-alert 5174],
an SU UMa-type dwarf nova, V725 Aql is now in ourburst.
It was revealed during the last outburst (vsnet-alert 3505, 3530,
1999 September) that the orbital period of V725 Aql estimated from
the superhump period is located at the middle of the period gap (2.5 hr).
V725 Aql is one of the most important object to study the CV evolution.
The last outburst is the first one in which the superhump was detected,
and so the supercycle has not precisely known yet while another outbursts
ware previously detected. Time-series observations are urgently needed
to clarify the nature of this outburst.
