Abstract

In the first section, we discuss our fits to the latest HiRes monocular spectra. We find that the best fit for the extragalactic component has a spectral index of γ = -2.38±0.04 with a distribution of sources varying with a evolution parameter m = 2.8 ± 0.3. In the second section, we discuss preliminary results from a new composition measurement using HiRes monocular data. We find a predominantly light spectrum above 10^17.6 eV.
