Solar region AR4405 has produced an X1.4 flare at 30/0319UT. This region is located in the southeast solar quadrant. A predominately east directed CME has followed. On UT day 30-Mar solar flare activity is expected to be R0, chance R1. S0 solar radiation storm conditions are expected. The solar wind speed is expected to be moderate to strong due to a solar coronal hole wind stream. G0-G1 geomagnetic conditions are expected. HF radio propagation conditions are expected to be fair to normal, with fair conditions during local night hours. Maximum usable frequencies in the Australian region are expected to be near predicted monthly values.
