SOHO Recovery Updates

Data was collected from several subsytems in preparation for the attitude recovery maneuver, which is planned for next week. New PLM temperature readings are attached. A test with transponder 1 indicates that the +Z low gain antenna is now also in the field of view of the Earth. Battery charge and propulsion subsystem temperatures are being maintained.
