PEM activation occurs during daylight only, when there is adequate power generated from the UARS solar array. Currently, testing is half-way completed, and the PEM magnetometer and medium energy spectrometers can activate under OBC control. Tests are now being conducted on the high energy particle spectrometers. Initial tests of these units show failure to enable high voltage power. The PEM team is investigating this result.
All science channels continue to provide excellent science data.
The MLS team will operate the instrument in a mode for diagnosing the reoccurance of slips in the antenna scan mechanism, and to attempt to find a method of operating the instrument which minimizes the impact of these slips on scientific data. We are currently evaluating operations in this new configuration. The MPG continues to assist the Project Scientist with the scheduling of instrument operations. Current plans do not include an interruption in service at the CDHF during this time period. The CDHF processed current day data through level 3 for all active instruments.
