This is great! Note that if it's near 9.7 mag it may still be rising.
The previous outbursts had maxima near 7 mag. See e.g.
http://saturn.sron.nl/~erikk/wzsge_1913_1946_1978.ps
Close monitoring from now on for the following few months would be nice to
find the bright humps at the orbital period in the beginning of the
outburst, the superhumps later on, and the rebrightening or not
(apparently the 1978 outburst showed nice rebrightenings, whereas the 1946
outburst did not. Also fast photometry is needed to see whether there are 
~30 sec (quasi-periodic) oscillations, which normally only appear in
quiescence.
