- SYNOPSIS OF ACTIVITY
- --------------------
-
- Solar activity was low. Region 7376 (N15W63) produced all
- of today's occasional small flare activity. This group has
- shown notable growth over the last 24 hours and displays fairly
- bright plage. Region 7381 (N04W25), the largest group on the
- disk, showed slight decay today and was stable.
-
- Solar activity forecast: solar activity is expected to be
- low.
-
- The geomagnetic field was at active to storm levels for the past
- 24 hours. Yesterday's disturbance developed into a minor storm
- at mid-latitudes. High latitudes ranged from minor to severe
- storm levels. Activity appeared to be declining since about
- 29/1800Z.
-
- Geophysical activity forecast: the geomagnetic field is
- expected to be mostly active tomorrow due to persistence of the
- current activity. Conditions should subside gradually to un-
- settled beginning on day two and should be at predominantly
- unsettled levels by the third day.

- A. Middle Latitudes
- Active 35/30/10
- Minor Storm 20/15/05
- Major-Severe Storm 10/05/01
-
- B. High Latitudes
- Active 35/30/10
- Minor Storm 25/15/05
- Major-Severe Storm 10/05/01
-
- HF propagation conditions became moderately to strongly
- degraded, most notably over the high and polar latitudes where
- auroral absorption and related anomalies resulted in disturbed
- ionospheric conditions. Minor improvements were reported late
- in the day as the geomagnetic storming ended. Conditions are
- expected to continue improving gradually over the next 24 to 48
- hours, returning to near-normal by about 01 January.
