A strong M7.9 solar flare erupted from Active Region 3098 at 09:49 UTC on September 16, 2022. The event started 09:44 and ended at 09:56 UTC.

The region is located on the west limb of the Sun, so even if coronal mass ejection (CME) was produced it would be directed away from our planet.

Solar activity is expected to be at low levels on September 16 and 17, with a continuing chance for R1-R2 (Minor-Moderate) radio blackouts. Very low levels are likely by September 18 as Region 3098 rotates off the visible disk.1

The geomagnetic field ranged from quiet to active levels due to transient influence over the past 24 hours.

It is likely to reach active levels, with a chance for G1 – Minor geomagnetic storm levels, on September 16 and 17 in response to negative polarity coronal hole high speed stream (CH HSS) influence.

Quiet to unsettled levels are likely on September 18.
