Ground-based telescopes have located the European Space Agency (ESA)/ NASA Solar and Heliospheric Observatory (SOHO) rotating at 1RPM in its nominal "halo orbit" between the sun and the earth, raising hopes that direct communications can be restored so that the tumbling craft's solar panels can be repointed to the sun.

The spacecraft went out of alignment on 25 June after three errors, according to ESA. Two of these were contained in command sequences on ground-system computers and the third was a decision to send a command to the spacecraft in response to unexpected telemetry signals.
