- SYNOPSIS OF ACTIVITY
- --------------------
-
- Solar activity was low. Region 7624 (N04W28) was
- responsible for three C-class flares including the largest of
- the period, a C5/1N at 01/0419UT. This region grew rapidly and
- also produced a number of B-class and subfaint flares through
- the period. Region 7627 (S07E57) is also growing at a good pace
- and produced a single C3/SF flare at 01/0705UT.
-
- Solar activity forecast: solar activity is expected to be
- low. Region 7624 and 7627 both have good potential for C-class
- flaring and an outside chance of producing an isolated M-class
- flare.
-
- The geomagnetic field has been at quiet to active levels
- for the past 24 hours at middle latitudes. High latitude
- stations saw minor to severe storming during the last half
- of the period. The activity is most likely the result of a
- well positioned coronal hole.
-
- Geophysical activity forecast: the geomagnetic field is
- expected to be unsettled to minor storm at middle latitudes and
- minor to severe storm levels at high latitudes for the next 24
- hours. Activity is then expected to be mostly unsettled to
- active for the remainder of the forecast period.
-

- Class M 15/15/15
- Class X 01/01/01

- Geomagnetic activity probabilities 02 dec-04 dec
-
- A. Middle Latitudes
- Active 15/20/30
- Minor Storm 30/20/20
- Major-Severe Storm 20/20/20
-
- B. High Latitudes
- Active 20/20/30
- Minor Storm 20/15/15
- Major-Severe Storm 45/25/25
-
- HF propagation conditions were not as significantly
- affected during the day as was previously forecasted due to the
- fact that the disturbance, which arrived near 12:00 UTC, failed
- to produce anticipated levels of geomagnetic activity.
- However, moderate to occasionally strong signal degradation was
- reported over the night-sector high and polar latitude paths
- with effects migrating as expected into the upper middle and
- some central-middle latitude paths. MUFs have decreased by up
- to 30 percent over many regions, with fading, multipathing, and
- absorption common causes of signal degradation. Conditions are
- expected to continue below-normal over the next 24 to 48 hours.

- NOTES:
- All times are in Universal Time (UT). Characters preceding begin, max,
- and end times are defined as: B = Before, U = Uncertain, A = After.
- All times associated with x-ray flares (ex. flares which produce
- associated x-ray bursts) refer to the begin, max, and end times of the
- x-rays. Flares which are not associated with x-ray signatures use the
- optical observations to determine the begin, max, and end times.
-
- Acronyms used to identify sweeps and optical phenomena include:
-
- II = Type II Sweep Frequency Event
- III = Type III Sweep
- IV = Type IV Sweep
- V = Type V Sweep
- Continuum = Continuum Radio Event
- Loop = Loop Prominence System,
- Spray = Limb Spray,
- Surge = Bright Limb Surge,
- EPL = Eruptive Prominence on the Limb.
