Indications are that the third and last gyro has been lost.
Sun-pointing attitude is maintained by intermittent thruster firings which are actuated and controlled by on board sun sensors. SOHO will remain in this mode until new software for a gyroless mode of operation has been developed. Due to insufficient roll control, SOHO cannot use its high gain antenna. The low gain omni-directional antenna is being used instead. Therefore no science data can be transmitted.
