Radiation (Geophysical Activity): The geomagnetic field is expected to be at quiet levels on day one (08 Oct), quiet to major storm levels on day two (09 Oct) and quiet to active levels on day three (10 Oct). Protons have a slight chance of crossing threshold on days one, two, and three (08 Oct, 09 Oct, 10 Oct). MP: Oct12 loads are out for review with reviews due by 5. ENG: No issues. GOT: No issues.
