Radiation (Geophysical Activity): The geomagnetic field is expected to be at quiet levels on days one, two, and three (28 Oct, 29 Oct, 30 Oct). Protons greater than 10 MeV: flux is anticipated to persist at background levels through 30 Oct. MP: Nov0226 loads should be out today for a review. ENG: No issues. GOT: No issues.
