VY Aqr superhumps:

  We have received VY Aqr observations from S. Kiyota, H. Maehara, Okayama
University of Science, and Kyoto University obtained between 30th
of Jun. and 2th of July.
 The period 0.06116(4)d is yielded from these data, and this is far
shorter than the superhump period known before, even the orbital 
period. Since the data of 2th of Jul seems to show the periodic variation 
whose period is near that known before, this strange period is due
to the precursor outburst phase.
