We present the precision measurement of the daily proton fluxes in cosmic rays from May 20, 2011 to October 29, 2019 (a total of 2824 days or 114 Bartels rotations) in the rigidity interval from 1 to 100 GV based on 5.5 x 10⁹ protons collected with the Alpha Magnetic Spectrometer aboard the International Space Station. The proton fluxes exhibit variations on multiple timescales. From 2014 to 2018, we observed recurrent flux variations with a period of 27 days. Shorter periods of 9 days and 13.5 days are observed in 2016. The strength of all three periodicities changes with time and rigidity. The rigidity dependence of the 27-day periodicity is different from the rigidity dependences of 9-day and 13.5-day periods. Unexpectedly, the strength of 9-day and 13.5-day periodicities increases with increasing rigidities up to similar to 10 GV and similar to 20 GV, respectively. Then the strength of the periodicities decreases with increasing rigidity up to 100 GV.

We are grateful for important physics discussions with Jonathan Feng and Igor Moskalenko. We thank former NASA Administrator Daniel S. Goldin for his dedication to the legacy of the ISS as a scientific laboratory and his decision for NASA to fly AMS as a DOE payload. We also acknowledge the continuous support of the NASA leader-ship, particularly William H. Gerstenmaier, and of the Johnson Space Center (JSC) and Marshall Space Flight Center (MSFC) flight control teams that have allowed AMS to operate optimally on the ISS for ten years. We are grateful for the support of Jim Siegrist, Glen Crawford, and their staff of the DOE including resources from the National Energy Research Scientific Computing Center under Contract No. DE-AC02-05CH11231. We gratefully acknowledge the strong support from CERN including Fabiola Gianotti, and the CERN IT department including Bernd Panzer-Steindel, and from the European Space Agency including Johann-Dietrich Worner and Simonetta Di Pippo. We also acknowledge the continuous support from Massachusetts Institute of Technology (MIT) and its School of Science, Michael Sipser, and the Laboratory for Nuclear Science, Boleslaw Wyslouch.
