- SYNOPSIS OF ACTIVITY
- --------------------
-
- Solar activity was very low. All of the regions on the
- disk were stable and quiet. A 10 degree filament near N26W29
- disappeared between 0444Z and 0635Z.
-
- Solar activity forecast: solar activity is expected to be
- very low to low.
-
- The geomagnetic field has been at quiet levels for
- the past 24 hours.
-
- Geophysical activity forecast: the geomagnetic field is
- expected to be mostly quiet for day one. A brief increase late
- on day one and early on day two is anticipated in response
- to a longitudinally narrow coronal hole. An additional in-
- crease is expected sometime on the third day in response
- another coronal hole which will be favorably positioned at
- that time.

- Geomagnetic activity probabilities 24 jan-26 jan
-
- A. Middle Latitudes
- Active 25/25/20
- Minor Storm 20/10/20
- Major-Severe Storm 10/05/10
-
- B. High Latitudes
- Active 25/25/25
- Minor Storm 20/20/20
- Major-Severe Storm 10/10/10
-
- HF propagation conditions were near-normal over all
- regions. Signals that crossed into the high latitude zones
- experienced poor signal quality during the night and early
- morning sectors (between 12:00 and 18:00 UT) due to a brief
- period of enhanced geomagnetic and auroral activity.
- Conditions are expected to be near-normal on 24 January.
- Gradual deterioration is expected thereafter as coronal holes
- begin to elevate levels of geomagnetic and auroral activity.
- High and polar latitude paths should be affected the most, with
- some fair to occasionally poor propagation possible over the
- upper middle latitude paths during the local night sectors
- (particularly on 26 January).
