Search for singularities of proton events in solar cycle 22 from ground-based observation data
Abstract
The characteristics of the increases in solar cosmic rays detected on the earth surface during solar cycle 22 are investigated using data of neutron monitors with a high time resolution. The event frequency in 1989-1991 exceeded the mean annual frequency (about 1/yr) for the entire period of solar cosmic ray observations by a factor of 4. The shape of the time profiles for a number of events is characterized by a two-hump structure, indicating the possibility of dual emission of solar cosmic rays from two different coronal sources.
