AQ Eri: superhump period

   Nakajima-san and Kiyota-san have reported further observations.
The superhump period determined from two nights' data was 0.06226(3) d.
Judging from the behavior up to now, the object may have undergone
a precursor outburst at the time of Stubbings's and ASAS detection.
The present superhumps were already present during the rising branch
from the temporary fading from the supposed precursor.

  Further observations are continuously needed to clarify the period
variation of the superhumps.
