This morning ACE p3 orbital fluence exceeded 1e9. ACE p3 rates have been decreasing since and ACIS recommendation is to continue with the loads because there are only 55ks remaining in this orbit, 30ks of which are with HETG and 5ks with HRC. Thus, the probability of exceeding the fluence of 2e9 is very low. MP: Dec1420A load review today at 2pm. Eng: No issues. GOT: No issues.
