Important notice about STEREO Behind

Arch to Nowhere

image135

The STEREO (Ahead) spacecraft watched as an eruptive prominence near the back of the Sun arched up but then headed back to the Sun's surface over a few hours (Sept. 19, 2010). Prominence eruptions occur fairly frequently and with both STEREO spacecraft now able to see most of the Sun, we do observe more of them.
