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.
