General Notes 1) The moon intrusion angles during the momentary horizon sensor events are no longer being reported since these are only the horizon sensor outputs as a result of the moon intrusions. With the satellite inertia to be overcome, and given the response time of the attitude control system (the time required to spin up the momentum wheels and turn the satellite), any momentary moon intrusion has likely ended before anything more than a negligible spacecraft motion occurs.
2) Yaw changes for battery and thermal management should not affect the users. All the individual changes may not be reported in this chart.
