increase geomagnetic activity from the current Quiet conditions,
possibly to Minor Storm levels. HF propagation conditions have been
degraded with depressed maximum useable frequencies. These depressions
are likely to continue over the next few days with periods of
disturbed ionospheric support for high latitudes. There is a chance of
