COMMENT: Degraded conditions were observed at times at high latitudes
during 10 March due to a Polar Cap Absorption event. Degraded
conditions have been observed since local dawn for mid-high latitudes
most likely the result of the mildly elevated geomagnetic activity.
Degraded conditions are expected at times for 11 March for mid-high latitudes,
returning to mostly normal to good conditions for 12-13 March.
