Additional Comments

Solar wind speed remains somewhat elevated due to Coronal Hole influence but this should continue to decline over the next few days and although it is possible the decline may not be entirely linear, we do not anticipate any significant change to the overall trend.
Solar activity has been low and there are no known Earth-directed CMEs. As a result, the outlook for geomagnetic activity over the next few days should be QUIET overall.
Time of forecast: 26 Dec 2025
