AB: An X3.8 class solar flare on 17Jan05 was immediately followed by large increases in energetic proton and electron fluxes within Earth's magnetosphere. Nuclear reactions from the impact of solar energetic particles on atmospheric constituents result in the emission of characteristic gamma rays, which are informative about the incoming particle spectrum. The first MINIS balloon, launched from SANAE in Antarctica (L=4), carried an x-ray spectrometer (energy range 0.05--10.0~MeV), and reached ceiling (35~km) about 5~hours after the flare ended, when GOES energetic particle fluxes were peaking. During this event, the MINIS balloon payload at high latitude, and the RHESSI high resolution spectrometer at lower latitude obtained spectra of atmospheric gamma emissions. We present and compare these higher and lower latitude observations.
