Shift M210 Start at 2000:049:12:30:00 GMT = 2000 Feb 18 7:30am EST End 2000 Feb 18 12:00pm EST SOT Lead Mark Freeman SOT SC/ACA Rob Cameron (briefly) FOT-SI Andy Northrup HRC-SI Mike Juda (briefly) ACIS-SI Yousaf Butt OTHER PLANS: Today:- Did not complete fine attitude initialization during long contact this morning, will complete tomorrow in 7am to 7pm pass. - Monitor spacecraft and environment, review CAPs for tomorrow's and Sunday's activities. Weekend: - Overall plan is to intercept at the beginning of the new (FEB20) load at 052:0145 (Sunday 8:45pm) to minimize the rebuilding of that load and avoid the need for a bridge load. Saturday the fine attitude init. will end with the spacecraft with the correct yaw angle for the initial observation of the FEB20 load. The first manuever of the load will then be a pure pitch to the observing attitude, which will replace the first segment of the "old" planned manuever and should not disturb the load timeline. Note: the pitch manuever cannot be performed Saturday because of earth obstruction between Sat. and the start of the load. - Rad zone passage 7pm Sat to 5am Sunday (EST). Will do CTI measurement in time after Sunday 9:30am (EST) pass and beginning of FEB20 load. - In Sunday COMM will do following activities: * Check EPHIN & ACE rates, If low enough then Enable RADMON Execute HRC CAP 566, sets initial conditions Execute ACIS CAP to initiate CTI measurement ******> NOTE: Sunday COMM has been extended to the left (earlier) Now planned for 14:30-17:45GMT, or 9:30am to 12:45pm EST. - FEB20 load products to be out today, review tomorrow. Note that this load should include an ACIS Stop Science at the beginning to end the CTI measurements started by the SI CAP. Coverage: Saturday - Bill Podgorski SOT Lead for Saturday PCAD/Fine attitude work @ 7am Rob Cameron plans to be in at 10am as Spacecraft/ACA Andy Northrup will be here at ~10am to help with setup CAPS Sunday - Ed Kellogg SOT Lead starting at ~9am Andy Northrup at ~9am to help run SI CAP(s) SI participation as req'd.

EVENTS DONE OBSID -------------- ---- ----- Start Shift 049:20:00 0 AOS - Status as expected 049:20:00 Mid-contact status nominal (see note 3) 049:20:36 Reviewed and signed CAP 571 (Pre Rad-belt activities) CAP 573 (Post Rad-belt SI activies) CAP 566 (HRC activities, called by 573) 049:21:12 LOS (see note 4) 049:21:30 End of shift 049:21:40 NOTES/ISSUES/PROBLEMS --------------------- (1) Note the earlier Sunday COMM above. This provides a better than 3 hour window to complete the activies, which should be plenty. (2) EPHIN Proton (and electron) rates are within acceptable bounds at the moment, but should be monitored tomorrow in anticipation enabling the RADMON process Sunday morning.
