Summary For December 25-31

Space weather remained at minor levels for the third consecutive week.
Isolated category R1 (minor) radio blackouts occurred on Dec. 26, 27,
and 29 due to medium-sized solar flares. The source of the flares was a
large, but structurally simple sunspot group. Category R1 radio
blackouts may result in the following system effects on the sunlit side
of Earth: minor degradation of high-frequency radio communication with
occasional loss of radio contact and brief degradation of low-frequency
navigation signals. No geomagnetic storms or radiation storms occurred
during the period.

Outlook For January 3-9

Space weather is expected to remain at minor levels. Isolated category
R1 radio blackouts are expected with effects comparable to those
mentioned above. Geomagnetic field activity is expected to increase
during Jan. 4 – 5 due to increased solar wind velocities, but is not
expected to reach geomagnetic storm levels. No solar radiation storms
are expected.
