M8.7 solar flare erupts from AR 3110

CME produced by M8-7 solar flare on october 2 2022 f

A strong solar flare, measuring M8.7 at its peak, erupted from Active Region 3110 (beta) at 02:21 UTC on October 2, 2022. The event started at 02:08 and ended at 02:21 UTC. The event comes several hours after impulsive M5.8 from the same region at 20:10 UTC on October 1.

A Type IV Radio Emission was detected at 02:27 UTC. Type IV emissions occur in association with major eruptions on the Sun and are typically associated with strong coronal mass ejections (CMEs) and solar radiation storms.

In addition, a 10 cm Radio Burst, with a peak flux of 148 sfu, was also associated with the event.

At this time, it doesn’t appear this CME had an Earth-directed component.

Solar activity is expected to be low, with a chance of M-class flares, over the next 2 days.

This will change as large AR 3112 (beta-gamma-delta) rotates toward the center of the disk.
