Radiation (Geophysical Activity): The geomagnetic field is expected to be at quiet levels on days one and two (03 Feb, 04 Feb) and quiet to minor storm levels on day three (05 Feb). Protons have a chance of crossing threshold on days one, two, and three (03 Feb, 04 Feb, 05 Feb). MP: Matlab test loads out for review. ENG: Pre-Approved CAPs for memory dumps. GOT: No issues.
