NOTE: The Effective Sunspot Number for 04 SEP 94 was 28.6. The Full Kp Indices for 04 SEP 94 are not available. The 3-Hr Ap Indices for 04 SEP 94 are not available. Greater than 2 MeV Electron Fluence for 05 SEP is: 2.5E+06 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.

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.
