Observations of the December 2006 solar energetic particle events with the Low Energy Telescope (LET) on STEREO
NASA's Solar-Terrestrial Relations Observatory (STEREO) was launched in October 2006 carrying an advanced payload of imaging and in situ instrumentation designed to study coronal mass ejections and associated soalr energetic particle (SEP) events and interplanetary effects. Included in the payload is a Low Energy Telescope (LET) designed to measure SEP composition, energy spectra, and anisotropics. This paper describes the LET sensor and measurements of the large solar eruptions of December 2006. These unexpected events fortunately provided opportunities to test the LET hardware and software and to cross-calibrate the LETs and several near-Earth instruments.
