The frequency of very short (i.e. normal) outbursts (latest
recorded one on Jan. 2) also indicated an SU UMa-type
classification.

 HW Boo superhump period

  Tonny Vanmunster, Itoh-san and Kiyota-san have reported
observations.

stage A: 0.0639(3) d since Feb. 4
stage B: 0.06236(4) d since Feb. 5

  The early development of ordinary superhumps
excludes a WZ Sge-type object.

  The published orbital period 0.06435 d is probably
in error.
