Using ASAS3 online data.  Probably good to a coupla points at five decimals.  Doesn't include outbursts.

Caveats : I'm not the best period analyst around, and when there are several peaks available as in this case I've been known to wrongly pick an alias instead of the period.  Not even sure if there wasn't a period jump at some point.  And I especially didn't like the value of a potential secondary period.

Also pretty much down near the noise here, it don't look like an artefact, but, ya know...  ...period04 reckons SNR at the signal is ~ 10 and one sigma at the signal is ~ 1.5 x 10^-5 but I did the rest of the work in AVE as I'm only just learning t'former.

Anyway, likely needs serious double checking.

And once the outburst is over people could follow it for a few days with some time series just to check for a period, even if there's no smell of superhumps or QPOs or whatever then, it is allowed.
