A Weekly Pattern from Hourly Estimates of the Super-Kamiokande-I   Neutrino Flux 1996-2001
  A search for a neutrino flux difference between weekdays and weekend days, for the average week of the Super-Kamiokande-I (SK-I) Experiment, was undertaken using the 5-day period version of the SK-I data taken from May 31st, 1996 to July 15th, 2001. A significant (p << 0.001) difference was found and the most obvious neutrino flux change from weekdays to weekend days can be summarized as follows: "Some neutrinos took the weekend off, especially on Saturday".
