Solar flare activity was very low over the last 24 hours. As
anticipated, solar wind stream stayed strong due to the continued
coronal hole effect. This coronal hole effect is expected to keep the
solar wind stream strong for the next two to three days. Very low
levels of solar activity may be expected from 24 to 26 December). As
expected, the geomagnetic activity remained enhanced on 23 December
due to the effect of the coronal hole. Mostly quiet to active levels
of geomagnetic activity may be expected on 24 December with some
possibility of isolated minor storm periods. Geomagnetic activity is
then expected to gradually decline to quite to unsettled levels with
the possibility of some active periods on 25 December, and then to
mostly quiet to unsettled levels on 26 December. Minor to mild
depressions in MUFs were observed today (23 December UT). Nearly
similar HF conditions may be expected on 24 and 25 December. MUFs are
expected to stay mostly near predicted monthly values on 26 December.
