27-day variations of the phase and amplitude of 1-st and 2-nd harmonics CR solar-daily anisotropy according to NM Mt. Hermon: effects in total intensity and different multiplicities
Abstract
After correction NM data on snow effect according to our work presented for Moscow COSPAR 40-th Assembly (Dorman et al. “Snow effect for total NM intensity and different multiplicities on Mt. Hermon during 1998 - 2014”) we determined 27-day variations in the phase and amplitude of the 1-st and 2-nd harmonics CR solar-daily anisotropy according to NM Mt. Hermon in total neutron intensity and different multiplicities. Obtained results for total neutron intensity we compare with results on other CR stations in dependence of altitude and cut-off rigidity. Results for different multiplicities we use for estimation rigidity spectrum of the CR 27-day variations in the 1-st and 2-nd harmonics CR solar-daily anisotropy. We estimate also the long-term changes in the 27-day variations of CR anisotropy and its connection with 27-day variations of solar activity.
