MTA Monitoring Report 05/09/03 - 05/15/03

Quiet.

From SOT shift report 2003-05-15 L1393: Discussion of RADZONE entry point held on [May 14]. Decision was to move radzone entry back to 12 hrs and 15 mins before perigee, from 13 hrs 15 mins. This saves 1 hr of observing time per orbit. If we had used this timing only one SCS107 trip would have occurred (last one) recently.

Our GOES monitoring is modified to comply with a NOAA SEC notice: Beginning 1500 UT on May 15, GOES-8 will become the primary satellite for protons. GOES 12 will be the primary satellite for magnetometer, X-ray, and electron measurements. GOES 10 will be the secondary satellite for all SEM sensors - magnetometer, X-ray sensor, and energetic particle sensor. This short-term solution (approximately 2 - 3 months) will be in place until we define and implement a permanent fix. A more detailed explanation can be found at: http://www.sec.noaa.gov/GOES.html.

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 8.467e-9 CTI/day
Detrended slope 8.732e-9 CTI/day

IRUs

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.

Recent Observations

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