Over a week ago, GONG far-side helioseismic maps forecasted the rotation of three prominent active regions to the front side in early November 2025. These regions have now emerged, contributing to a marked increase in magnetic activity. They are clearly visible in the latest line-of-sight magnetogram from a GONG site (top image).
After nearly two weeks of minimal activity, these regions produced two X-class and several high-energy M-class flares. It is noted that the X-class flares were observed after a gap of about four months. This flaring activity, along with associated CMEs, has also elevated the chances of auroral sightings on 6-7 November.
In the accompanying illustration below, the top panel shows newly assigned active region numbers, while the bottom panel references their previous front-side identifications during far-side transit.
