Low solar flare activity is expected on 18-Apr, with a chance of
moderate activity. The solar wind is light to moderate and likely to
increase later on 18-Apr with the arrival of a coronal hole high speed
wind stream. Geomagnetic conditions are quiet after unsettled to
active periods on 17-Apr, and are likely to reach active levels again
on 18-Apr with the onset of coronal hole effects. Disturbed
geomagnetic conditions over the last few days have resulted in
degraded HF propagation conditions and depressed maximum useable
frequencies, which are likely to persist until 20-Apr.
