A week of intense solar activity: 2 X- and 25 M-class flares, with 2 Earth-directed CMEs

The period of January 9 to 15, 2023, was marked by intense solar activity, with numerous M and X-class flares being observed. The largest event of the period was an X1.9 flare on January 9, followed by an X1.0 on January 10. There were a total of 2 X-flares and 25 M-flares during the period but only two Earth-directed CMEs were observed from this flurry of activity.

Increased solar activity – glancing blow possible on January 19

Solar activity reached high levels in the past 24 hours, with the strongest event being an M6.0 flare from Region 3191. This event was accompanied by a Type II radio sweep and a Coronal Mass Ejection (CME) signature, however, analysis and modeling indicate that no Earth-directed component was produced. A CME was also observed off the southwest limb at 22:00 UTC on January 14, with analysis and modeling suggesting the possibility of a glancing blow on January 19.

Solar filament eruption, possible glancing blow on November 29

A solar filament was observed lifting off the Sun's northeastern quadrant beginning at approximately 04:45 UTC on November 25, 2017. An associated weak Coronal Mass Ejection (CME) was observed in SOHO/LASCO C2 and C3 imagery and the analysis shows a potential…
