Shown here are the latest SECCHI beacon images.


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 of the large compression factors used, these beacon images are of much lower quality than the actual science data. Same data as rotating GIF movie The images above are shown in the order of the relative positions of the three viewpoints, Behind, Earth, and Ahead. 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 We would also like to acknowlege the past assistance from the following organizations: Rutherford Appleton Laboratory: Chilbolton, UK In addition, we wish to acknowlege.

Selected Figures from the SEM. Here is a comparison of SEM and GOES X-ray data for a randomly chosen, moderately active day (15 May 2001).

Selected Figures from the SEM

A selected list of solar X-ray events observed by CELIAS/SEM (15 second averages) 25 Feb 2014 (DOY 056 0039 UT) X4.9 x-ray flare in AR1990 with a 2B optical flare at S12E82 leading to a shock 63.5 hours later on 27 Feb 2014 (DOY 058) at 1617 UT. 07 Jan 2014 (DOY 007 1840 UT) X1.2 x-ray flare in AR1944 leading to a shock 49.5 hours later on 09 Jan 2014 (DOY 009) at 1933 UT.

Solar Cycle Progression and Prediction

The charts and tables are updated by the Space Weather Prediction Center monthly using the latest ISES predictions. Observed values are initially the preliminary values which are replaced with the final values as they become available. Solar Cycle 24 Prediction Update released May 8, 2009 May 8, 2009 -- The Solar Cycle 24 Prediction Panel has reached a consensus decision on the prediction of the next solar cycle (Cycle 24). First, the panel has agreed that solar minimum occurred in December, 2008. This still qualifies as a prediction since the smoothed sunspot number is only valid through September, 2008. POES Energetic Particles. GOES Solar X-ray Imager. NOAA / Space Weather Prediction Center GOES Solar X-ray Imager NOAA National Weather Service Space Weather Prediction Center The GOES 12 through 15 spacecraft each carry a sophisticated Solar X-ray Imager to monitor the Sun’s X-rays for the early detection of solar flares, coronal mass ejections, and other phenomena that impact the geospace environment.

This early warning is important because travelling solar disturbances affect not only the safety of humans in high-altitude missions, such as human spaceflight, but also military and commercial satellite communications. In addition, coronal mass ejections can damage long-distance electric power grids, causing extensive power blackouts. Organizations Participating in the GOES SXI Program.

Colored dots represent photospheric footpoints of open field lines, with different colors used to indicate the expansion factors fs (or solar wind speed v) associated with the flux tubes. Areas shaded light gray (dark gray) are closed field lines with Br > 0 (Br < 0). The crosses mark the daily position of the subearth point on the maps (Sun). Since the Sun's rotation axis is inclined 7.25o to the ecliptic, over the course of a year the subearth point varies (in latitude) from +7.25o above to -7.25o below the Sun's equator. The x-axis is Carrington Longitude in degrees. Le logiciel Heliocentrique v 1.3.
