IA. Analysis of Solar Active Regions and Activity from 31/2100Z
to 01/2100Z: Solar activity was very low. No flares were detected.
The visible disk was spotless.
IB. Solar Activity Forecast: Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 31/2100Z to 01/2100Z:
Geomagnetic field activity was at quiet to unsettled levels. ACE
solar wind measurements indicated Earth remained within a recurrent
coronal hole high-speed stream. Solar wind velocities gradually
decreased from 538 to 413 km/sec during the period.
IIB. Geophysical Activity Forecast: Geomagnetic field activity is
expected to be at quiet to active levels during day 1 (02 January).
Activity is expected to decrease to quiet to unsettled levels during
days 2 - 3 (03 - 04 January) as the high-speed stream subsides.
