SYNOPSIS OF ACTIVITY
--------------------
Solar activity was very low. All regions on the
disk were stable and quiet.
Solar activity forecast: solar activity is expected to be
very low to low.
The geomagnetic field was mostly quiet to unsettled. High
latitudes experienced some isolated minor storm periods from
0900-1800Z.
Geophysical activity forecast: the geomagnetic field is
expected to be predominantly unsettled for the next 24 hours.
Conditions should be at quiet to unsettled levels for the
second and third days.
Event probabilities 21 jan-23 jan
Class M 05/05/05
Class X 01/01/01
Proton 01/01/01
PCAF Green
Geomagnetic activity probabilities 21 jan-23 jan
A. Middle Latitudes
Active 25/10/10
Minor Storm 10/05/05
Major-Severe Storm 05/01/01
B. High Latitudes
Active 35/10/10
Minor Storm 15/05/05
Major-Severe Storm 05/01/01
HF propagation conditions were normal over most regions.
Some high latitude stations reported isolated minor signal
degradation, although nothing significant occurred. Similar
conditions are expected to persist for the next 72 hours.
Propagation should increase in stability on 22 and 23 January,
particularly for transpolar paths.
