NSV 1440: superhump period

     Josch Hambsch and Petter Star have reported the observations. The superoutburst
has gradually faded from about 13 mag to 14.1 mag until Feb. 20. On Feb. 20, we can
see the beginning of a rapid fading. The object has show superhumps with a constant
period of 0.025343 (6) d and amplitudes of 0.05 mag.
     In 2015 and 2017 superoutbursts, this object showed eight rebrightenings whose
intervals are 7-9 days. However, the behavior of this superoutburst is significantly
different from the previous ones. Further monitoring is strongly encouraged.
