Very low levels of solar activity are expected for today, 25 July. The
solar wind speeds are strong due to the arrival of a high speed wind
stream from a recurrent coronal hole. Geomagnetic activity is expected
to be at unsettled to active levels. High-frequency radio
communication users are advised to use near predicted monthly
frequencies. Periods of moderately degraded HF propagation conditions
are possible at high latitudes.
