Solar Flares Possible as Major Sunspot Regions Rotate Into View
Researchers expect two regions to be in clear view by December 30–31 with low odds of Earth-directed disturbances.
Overview
- After roughly two weeks of quiet, the IKI RAS Solar Astronomy Laboratory reports signs of renewed flaring activity on the Sun.
- Bright magnetic loops on the eastern limb indicate two large active regions are emerging, with their sunspots expected to appear within one to three days.
- The year’s largest sunspot complex, numbered 4294/4296/4298, could reappear on the southern hemisphere within a day and may cover a smaller area than before.
- A region near the northern hemisphere identified with AR 4274 could return, though scientists doubt such long persistence even as they note its history of long-duration flares and strong plasma ejections.
- The laboratory estimates only about one in ten flares produces a geomagnetic storm, suggesting limited likelihood of significant effects on Earth during the holiday period.
