The Stereo Mission


UCLA provides plots and ascii files of Level 1 to Level 3 data.

Level 1 Magnetometer Data
Three time resolutions of STEREO data are available.
32 Hz burst mode - not continuous - least priority for telemetry.
8 Hz normal highest rate data.
1 Hz overlapped 2-second averages.
These data are available in spacecraft coordinates and in RTN coordinates for all of the mission to date.
Use heliocentric_level1_magnetic_field
During 2006 the data are also available in GSM coordinates.
Use earth_orbit_phase_magnetic_field

Level 2 Measurements of the IMPACT Instrument Suite
Data from the magnetometer and the PLASTIC plasma analyzed are available at 1m, 10m, and 1 hr resolution in RTN coordinates. Use level2_plasma_and_magnetic_field

Level 2 data and plots from LET are available at LET data server

Level 2 data and plots from HET, LET, and SIT are available at http://www.srl.caltech.edu/STEREO/index.html

The IMPACT Investigation

The IMPACT (In-situ Measurements of Particles and CME Transients) investigation targets the major STEREO science goals of 3D corona and solar wind structure, CME origins and interplanetary (ICME) evolution, Solar-terrestrial coupling, Solar Energetic Particle acceleration, and the solar magnetic flux cycle. IMPACT's strategy uses comprehensive in-situ measurements to complement the STEREO images, together with models to tie the in-situ measurements and images together.

Our international teaming approach has enabled the IMPACT investigation to include both plasma electron and energetic particle instruments determine the bulk parameters of the solar wind electrons and the flux and energy distribution of energetic particles from solar wind energies up to many MeV, including elemental abundance. The combined instrument package is capable not only of determining the strength and orientation of the magnetic field within ICMEs and the ambient solar wind at two different locations, but also determines whether the local field is rooted at the Sun at one or both ends or is disconnected from the Sun entirely. Suprathermal electron and ion detectors included in the IMPACT package add the capability to determine whether the local magnetic connections to the Sun include flaring active regions. The SEP instruments provide directional information important for both remote-sensing shock location and shape, and determining SEP maximum fluxes in cases where there is considerable anisotropy not in the direction of the nominal Parker Spiral as occurs during passage of ICMEs. In addition, a coordination with the Bougeret SWAVES investigation links in the radio remote sensing observations that herald oncoming major events, enhances STEREO science return by enabling coupled in-situ measurements by the antennas and plasma/field instruments.
