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.

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.
