Radiation (Geophysical Activity): The geomagnetic field is expected to be at quiet to unsettled levels on day one (07 Oct), quiet levels on day two (08 Oct) and quiet to major storm levels on day three (09 Oct). Protons have a slight chance of crossing threshold on days one, two, and three (07 Oct, 08 Oct, 09 Oct). MP: No issues. ENG: No issues. GOT: No issues.
