Eng: - CAP 425H sequencer self-test ran nominally ACIS: - CAP 1150 was succesfully run to uplink ACIS Flight SW Standard E, Optional E using SOP_ACIS_SW_STDEOPTE. In step 8 of the SOP there was an incomplete uplink of a patch command load with 32 of 33 blocks reaching the spacecraft. This resulted in the ACIS FIFO being stuck waiting for the rest of the upload, which was cleared by executing an ACIS warm boot. After this the SOP was restarted at step 4 and ran nominally to the end. - The ACIS team and FOT will be updating the procedure to account for the possibility of a failed command upload and looking for other methods to mitigate this possibility. - The ground team will be investigating to determine if this event was consistent with known system performance that occasionally results in an incomplete command load uplink. Radiation: - Solar Activity Forecast: Solar activity is expected to be very low, but there is a chance for an isolated C-class event from Region 1061. - Geophysical Activity Forecast: The geomagnetic field is expected to be active for the first day (07 April) due to a favorably positioned coronal hole. Activity levels are expected to be unsettled to active on the second day (08 April) due to persistence as well as possible effects from today's CME. Predominantly quiet levels are expected on the third day (09 April).
