Solar Wind and Suprathermal Ion Populations at the STEREO Spacecraft Approaching Solar Minimum
Abstract
The two STEREO spacecraft, which were launched in October 2006, have been gradually separating in longitude at a rate of about 22 degrees per year. During this past year, the dominant heliospheric features have been a series of recurrent high and slow speed solar wind and their interaction regions, an occasional transient event (e.g., May 22), and "background" suprathermal populations such as interstellar pick up ions. In this poster we present an overview of the plasma and suprathermal signatures observed by the STEREO spacecraft using data from the Plasma and Suprathermal Ion Composition (PLASTIC) and Magnetometer (IMPACT/MAG) investigations. Complementary STEREO PLASTIC related presentations in this session are by Popecki et al., Klecker et al. (invited), and Simunac et al.
