I noticed your question and TK's reply. But both of you know what the dates
and durations were - the rest of us don't. So I'm not sure what TK is really
saying, or what you're asking. Could you elaborate a little? I think the
interval you should be considering is between successive normal outbursts - the
superoutburst is a completely different event which - from an observational
viewpoint - doesn't affect the normal outbursts much. There seems to be a
shortening of the cycle and a reduction in amplitude, but this is not as evident
in the systems with fewer normal outbursts.
What is this 'complete cleaning' phase you mention involving hydrogen? This
seems more of a nova phenomenon.

behaviour
Hi,
WX Hyi has just shown the following sequence of events in
succession
1. normal outburst
2. superoutburst
3. another normal (?) outburst, ongoing at this moment.
Phases 1 and 2 do occur in succession with other systems too.
However event 3 seems a bit out of phase. The going theory spells that
the superoutburst is the 'complete cleaning' phase, iow all H is burned away.
What happens to WX Hyi then for it still to have another outburst? Is it
unstable mass transfer by the secondary triggered by the past s/outburst or is
it due to another unrelated activity?
Do I hear 'flickering'?
Regards,
Berto Monard
