OT J122221.6-311525: started fading!
We have received further data from Kiyota-san and Josch Hambsch.
Hambsch's data on Feb. 13 show a rapid fading. The second plateau
lasted for ~30 days. The superhump period during the final part
of the second plateau is 0.07646(1) d. The same periodicity
was observed during the rapid fading, but with some hint of
phase variation (double maxima). Observations are strongly
encouraged to record how these superhumps evolve during
the post-superoutburst (and potential rebrightning) stage.
