Five solar neutron events were detected by the ground-based neutron monitors in association with five solar flares with deviations greater than 5σ from the background fluctuations in solar cycle 23. Together with these five solar neutron events and five events detected in former solar cycles, there are a total of ten solar neutron events observed by ground-based detectors. Using these data, we report on some of the properties of the solar neutron events as neutron and proton spectra, flare positions where solar neutron events were produced, and the relation between neutron flux and flare class.
