 VX For: likely emergence of ordinary superhumps

Itoh-san, Berto Monard, Josch Hambsch, and Peter Nelson reported further
observations of VX For.
Observations on 22nd Jan. by Berto Monard showed single-peaked variations
for two cycles. This is likely the emergence of ordinary superhumps.

Its period is around 0.06d, which is roughly consistent with superhumps
observed in its previous outburst in 2009.
Further observations are requested to confirm the Stage A superhump period.

Best,
Yusuke
