Solar activity on UT day 14-Feb is expected to be at R0-R1 levels. S0 solar radiation storm conditions are expected. The solar wind speed is expected to be strong to moderate. G0-G1 geomagnetic conditions are expected due to coronal hole high speed wind stream effects. HF radio propagation conditions are expected to be mostly fair. Maximum usable frequencies (MUFs) in the Australian region are expected to be near predicted monthly values to 15% depressed. Shortwave fadeouts are possible.
