On UT day 5-Oct solar activity is expected to be R1-R3 with a slight chance for R4. The solar wind is expected to become strong to very strong. G3 geomagnetic conditions are expected, with a chance for G4, due to multiple anticipated CME arrivals. S0-S1 solar radiation storm conditions are expected. HF radio communication conditions are expected to become degraded with the arrival of the CMEs. Maximum usable frequencies are expected to become up to 15% degraded after the CME arrivals. Auroras are likely during local night hours at high latitudes, possibly reaching mid-latitudes.
