MTA Monitoring Report 04/18/03 - 04/24/03

Quiet --- LASCO/EIT observed a partial halo CME on 2003/04/23.

Detrended CTI

CTI analysis is now computed with "detrending":
Detrend CTI = Measured CTI + S3 amplitude reject rate * Detrend factor.

Average of ACIS-I CCDs (MnKa) slope 8.527e-9 CTI/day
Detrended slope 8.792e-9 CTI/day

The IRU-1 gyro-1 current has settled around 151-153 mA and become less noisy during this period. The gyro bias level has remained unaffected by the change in current and so to date, there has been no impact to science or operations. The procedure and products to perform a swap to IRU-2 were approved last week by the Flight Director Board and are available in the event they are needed.

Reaction wheel speeds have occasionally dropped below the limit of 52.4 rad/s due to our increased momentum envelope.

"Prob" means that there was probably bad time data included in the manual runs. This will be corrected in future processing.
