EPH temp 85.17 DEG F NOTES/ISSUES/PROBLEMS Be alert for continued "puffed up" radiation belts. We may find SCS 107 triggered when we get comm at 1205 GMT tomorrow. From the 9am status meeting: Three supports over the last day. 1850-2050 pass was cut short for ratty telemetry, however we acquired all data. But plan to repeat dump on the upcoming 34m pass. Filed two DR's against DSS-16: for unknown CFC increments; and couldn't lock at 256kps but did lock at 512kps. Ran CAP 675 to re-enable SCS 107, and CAP 898 to set the short eclipse flag for the last eclipse of this season, at roughly 1500 tomorrow. Tomorrow will need to run the CAP to reset the eclipse flag to medium. AUG0204C products are out this morning for a load review at 1:00 pm EDT. Products had to be reworked for continuity with the radiation re-start, and for a TOO.
