SYNOPSIS OF ACTIVITY
--------------------
Solar activity was low. Region 7773 (S09W05) produced the
largest flare, a C6/1F at 05/0538Z. This region has reduced
spot area but increased magnetic complexity since yesterday.
Region 7776 (S08E23) has been relatively quiet. New Region 7777
(S14W22) was numbered.
Solar activity forecast: solar activity is expected to be
low. There is still a chance of an isolated M-class flare in
Region 7773 or 7776.
STD: A 245 MHz radio noise storm was observed from 02:15 UTC to
about 09:27 UTC. Another full-disk Yohkoh x-ray image has been
appended to this report showing the location of the coronal
hole and the relatively strong emissions from Regions 7773
and 7776.
The geomagnetic field was quiet to unsettled at most
locations. Active to minor storm periods were observed at some
high latitude stations.
Geophysical activity forecast: the geomagnetic field is
expected to be active within the next 48 hours in response to
a coronal hole.

HF propagation conditions were normal over all regions.
Minor signal degradation is expected to begin perturbing
high-latitude paths (particularly transauroral circuits) over
the next 2 to 3 days. Conditions may also gradually
deteriorate for middle latitude paths, although in general only
minor signal degradation is expected.

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.
