With no sunspots producing strong flares, the sun is officially quiet. But although the sun is officialy “quiet” multiple C-Class flares have been detected within the past 24 hours. C-Class flares continue to be detected around various locations on the visible solar disk, including a long duration C3.6 Flare that took place around Sunspot 1356 in the northwest quadrant Wednesday evening. The special event today is the solar prominence on the eastern limb – about 7 times the size of Earth.

No new regions were numbered on Wednesday. A solar filament appears to have lifted off the Sun at the same time and this may have produced a Coronal Mass Ejection (CME). There will remain the risk for an isolated M-Class flare on Thursday, 15 % propability. In the latest NOAA/SWPC solar forecast from Nov. 30 there is a possibility of coronal hole high speed stream effects from the southern polar extension coronal hole.

NOAA forecasters estimate a 25% chance of geomagnetic activity around the poles today as a solar wind stream buffets Earth’s magnetic field. High-latitude sky watchers should be alert for auroras after nightfall.
