July 09, 2000 1900 UT SOLAR ALERT HELIOSYNOPTICS, BOULDER, COLORADO EXTREME FLARE ACTIVITY EXPECTED FROM SUPER-REGION 9077 Potential-super-region 9077 (N18 E63) is expected to produce numerous strong flares for the next 10 days, at least. Some of these events will produce serious geophysical effects, including intense radio interference and high levels of proton particle fluence. This region has the size and structure unique to the most powerful regions of past solar cycles. X-class events are certain to occur. Some of these could exceed X9 intensity, depending on further growth and motions within this special sunspot group. A strong and possibly-growing delta configuration exists in this region, not yet clearly reported by the observatories with magnetographs. H-alpha structures permit detection of the complex field configuration even close to the solar limb. Proton fluence will be relatively low from any large events until solar rotations brings this region into favorable alignment with Earth in about a week. A coronal hole NW and adjacent to this region will assist access of ejecta and particles to the Earth environment. The predictions of times and intensities of events are impossible until there is a longer record of rates of change in this spot group. The presence of unusually dark penumbra and a multipolar, non-potential field configuration promise there will be serious eruptive events. Patrick S.
