Important notice about reduced STEREO
Latest SECCHI beacon images
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. For the Heliospheric Imager (HI)
images below, the order is reversed to reflect the fact that the HI Ahead
telescopes look to the left of the Sun, and those on Behind look to the right.
Also, the HI images are not rotated to put solar north up.
The data on this page include telemetry collected by the following
