I have used the available data to check
the cycle length of PG0943+521 as
far as possible with regard to the limited coverage.

I have found 10 supermaxima from 1/1993 to 12/1994
(missing possible 7 maxima).
The cycle length is ~42-45days for a superoutburst and ~4-5days for
normal outbursts (most normal outburst are missed).

The duration of a superoutburst is ~15-20days.
PG0943+521 rises in 1-2days from ~15mag to ~12.0-12.2mag,
stays there for 1-3days and fading than to 
12.8-13.3mag before finally fading to minimum in 1-2days.

But be cautious, this lightcurve analysis based
on a visual estimates taken from VARSTARS, VSNET with
limited temporal coverage.

Regards, Jochen
