Summary Forecast
Wednesday 15 October
last updated 14/2317 UT
Solar activity on UT day 15-Oct is expected to be at the R1-R2 level, as two magnetically complex solar regions are currently on the solar disk. S0, chance S1 solar radiation storm conditions are expected. The solar wind speed is expected to be moderate with an initial declining trend as the recent influence of a coronal hole wind stream continues to abate. The solar wind speed and the interplanetary magnetic field are then expected to become enhanced due to the arrival of a weak CME later in the UT day. G0-G1 conditions are expected on 15-Oct associated with the weak CME arrival. HF radio propagation conditions are expected to be initially normal, becoming fair. Maximum usable frequencies (MUFs) in the Australian region are expected to be generally near predicted monthly values, with 15% depressions at times for the southern Australian region. Shortwave fadeouts are possible.
