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. Realtime resources:     Browse resources: latest SECCHI beacon images.

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.
