Summary Forecast
Friday 23 February
last updated 22/2321 UT
An R3 (X6.3) flare was observed at 22/2234UT, with a strong HF fadeout impacting the south Pacific region. Further HF fadeouts are likely. On UT day 23-Feb solar activity is expected to be R2-R3, due to a large flare active solar region currently located in the northeast solar quadrant. The solar wind speed is expected to be light. G0 geomagnetic conditions are expected. Moderate to possibly strong solar wind conditions are expected from late on 24-Feb due to the anticipated arrival of a component of a mostly west directed CME. G1 conditions are expected during the first half of 25-Feb. Maximum usable frequencies (MUFs) are expected to be near predicted values to 15% enhanced. Moderately degraded HF conditions are expected on 25-Feb for the southern Australian region. Northern Australian region MUFs are expected to remain near normal.
