OT J122221.6-311525: superhumps grew!

   During the current rebrightening, the new observations by
Kiyota-san and Josch Hambsch have shown the regrowth of superhumps.
(So these superhumps appear to be newly excited).
Although the period is still hard to determine, the best period
on the two-night basis is 0.0681(3) d, allowing aliases.
The mean amplitude during the rebrightening maximum was 0.06 mag.
Further observations are still very encouraged.
