- 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.
