Solar Energetic Particle Fluences December 26, 2001 Event Based on Data from ACE/EPAM; GOES-8,11,&12; and SAMPEX/PET Note: Statistical Uncertainties on GOES and EPAM data are negligible. To account for systematic uncertainties in combining data from different sensors we add 20% in quadrature with the statistical uncertainties Fluence Spectra Start: 0500 UT on 12/26/2001 End: 2300 UT on 12/28/2001 Compiled by R.
