Dumps of the on-line and off-line OBC checksummed memories associated with CAP 1418: - 750 AG, 122/0349z - 750 AH, 122/0408z - 0750 AI, 122/1120z - 0750 AM, 122/1138z FOT Ops and Engineering Sim today 0915-1630LT Radiation: Solar activity is expected to be very low with a slight chance for a C-class flare on days one, two, and three (02 May, 03 May, 04 May). MP: Nothing to report. Eng: Software patch to update the measurement residual threshold should mitigate some of the aspect camera issues related to hot pixels. So far the performance is normal. GOT: No issues.
