  Super-Kamiokande(SK) is a real-time detector capable of measuring the exact
time of solar neutrino events. This, combined with a relatively high yield of
these events of roughly 15 per day, allows a search for short-time variations
in the observed flux. Using all 1496 days of SK-I's solar data, we looked for
periodic variations of the observed solar neutrino flux, and found no
significant periodicity.
