COMMENT: HF conditions are currently enhanced due to high levels 
of ionising EUV flux from multiple sunspot regions. Geomagnetic 
activity over the next two days may reduce the maximum useable 
frequency, however conditions are not expected to drop significantly 
below the forecast monthly values.
