Important notice about reduced STEREO science operations
The STEREO Ahead spacecraft is currently operating on
the first side lobe of the high gain antenna. See this
important notice for more information.
Communications with the STEREO Behind spacecraft were interrupted on October 1,
immediately after a planned reset of the spacecraft performed as part of a test
of solar conjunction operations. The cause of the anomaly is not yet known,
though a sensor anomaly in the guidance and control system is suspected.
Attempts to recover the spacecraft are continuing.
