- 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.
-
- Event probabilities 06 sep-08 sep
-
- Class M 20/20/20
- Class X 01/01/01
- Proton 01/01/01
- PCAF Green
-
- Geomagnetic activity probabilities 06 sep-08 sep
-
- A. Middle Latitudes
- Active 20/30/30
- Minor Storm 10/20/20
- Major-Severe Storm 05/10/10
-
- B. High Latitudes
- Active 20/30/30
- Minor Storm 15/20/20
- Major-Severe Storm 05/10/10
-
- 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.
