m2.5 solar flare july 8 2022

A long-duration M2.5 solar flare erupted from AR 3053 at 20:49 UTC on July 8, 2022, producing a partial halo coronal mass ejection (CME).

The event was associated with multiple discrete radio bursts, including a 230 sfu Tenflare as well as a partial halo CME first observed at 20:48 UTC in coronagraph imagery.

The majority of the ejecta appeared to be directed eastward, however, the preliminary analysis indicated the possibility for a glancing blow early to mid-day on July 11.

Solar activity is expected to be low with an increased chance for M-class flaring (R1-R2, Minor-Moderate) through July 11, particularly from Regions 3053 and 3055.
