Solar Energetic Particle Fluences January 17, 2005 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: 1000 UT on 1/17/2005 End: 0600 UT on 1/20/2005 Compiled by R.
