The coronal mass ejection (CME) that left the Sun on 10th Sep arrived this morning, 12th Sep. The CME carried significant southward interplanetary magnetic field, and the disturbance is currently ongoing, causing geomagnetic G2 STORM conditions.
The Sun has continued at moderately active levels with multiple M-class flares, an X-class flare, and several CMEs in the last few days. We anticipate at least one of the CMEs to be Earth-bound, and arrive early in the morning of 14th Sep. This is likely to result in prolonged enhancements in geomagnetic activity, hence further STORM periods could follow.
Assuming clear dark skies, there is an increased chance of seeing the aurora from 12th to 14th Sep. Those in Scotland, northern England and Northern Ireland have a better chance if the weather is favourable.
