V1454 Cyg superhumps update

  Josch Hambsch and Maehara-san have reported further observations.
The amplitudes of superhumps have decreased.  The mean superhump period
up to now is 0.05770(4) d.  A preliminary O-C analysis has yielded
a positive period derivative of dot(P)/P = +13(4)*10^(-5).
The values are similar to those of SW UMa.
Since superhumps are expected to grow again, further continued observations
are encouraged.
