Orbital fluence is 1.1e7 vs. threshold 1.0e9. Chandra is in the solar wind, but the ACE proton rates are low and slowly decreasing. 3) SOT GRETA workstation. The SOT GRETA workstation had problems because GRETA directories were not being mounted from the computer twinkie. The problem was eventually solved by the following steps: - forcing the export of the GRETA disks to mos002 (the SOT GRETA workstation - stopping and restarting the automounter on mos002 - re-exporting the GRETA disks to mos002. 4) The CAPs for the LETG insertion on 2000:296 and LETG retraction on 2000:299 were reviewed and approved. 5) The OPSIM model of the OTGs were exercised by running LETG insertion and retraction scripts from the third string OFLS. The model telemetry looked mostly correct on the EHS OTG mechanism display. Telemetry capture to GRETA and delog of products will be used to further verify the OPSIM model in another test. 6) Quick Look data review (OK unless noted): Seq # ObsID Target SI Grat Comments -------------------------------------------------------- There were no new quicklook datasets during this shift.
