Important notice about STEREO Behind

PLASTIC suffered a high voltage anomaly on December 5. The instrument is in the process of being recovered to full operating mode, which is expected to take several days. Until this process is completed, PLASTIC data should be considered as untrustworthy.

STEREO In-Situ and Radio Space Weather Beacon Data

Shown here are plots of the latest in-situ particle and fields data from the STEREO IMPACT and PLASTIC instruments, and radio data from SWAVES. The STEREO space weather beacon telemetry mode is a very low rate, highly compressed data stream broadcast by the spacecraft 24 hours per day. These data are used for space weather forecasting. Because the data are produced in real-time, the calibrations may not match those used for the final data product.

Radial-Tangential-Normal (RTN) coordinates are defined such that the +X axis points from sun center through the satellite (radial), and the +Z axis points along the projection of the solar North pole (normal). The +Y axis completes the right-handed coordinate system, and points towards the solar West limb (tangential).

The data on this page include telemetry collected by the following organizations:

  • NASA Deep Space Network
  • National Institute of Information and Communications Technology: Koganei, Japan
  • Centre National d'Etudes Spatiales: Toulouse, France
  • Amateur station DL0SHF, Kiel-Ronne, Germany
  • AMSAT-DL/Bochum Observatory, Germany
  • Johns Hopkins University Applied Physics Laboratory, Laurel, MD, USA
  • Korean Space Weather Center, Jeju, South Korea

We would also like to acknowlege the past assistance from the following organizations:
  • Rutherford Appleton Laboratory: Chilbolton, UK

In addition, we wish to acknowlege

  • Amateur station KA9Q, Phil Karn, for writing and donating the decoding software used at the ground stations.
  • NOAA Space Weather Prediction Center for organizing and scheduling the ground station network.
