Moderate solar flare reaching M1.7 erupted from AR 1652

Moderate solar flare reaching M1.7 erupted from AR 1652

A second moderate solar flare erupted on January 13, 2013 from AR 1652. M1.7 solar flare peaked at 08:38 UTC. The event started at 08:35, peaked at 08:38 and ended at 08:40 UTC. Type II and IV radio emissions were associated with the event. Type II emissions occur in association with eruptions on the sun and typically indicate a coronal mass ejection is associated with a flare event. Type IV emissions occur in association with major eruptions on the sun and are typically associated with strong coronal mass ejections and solar radiation storms.

Earlier today the same Active Region 1652 classified with beta-gamma-delta magnetic configuration generated an M1.0 solar flare  at 00:50 UTC. AR 1652 generated 2 M-class and 20 C-class solar flares in the past 24 hours.  Considering the position of Sunspot 1652, which is facing Earth, geoeffective CME is possible.

There are currently 9 numbered sunspots with AR 1652 and AR 1654 capable of generating more M-class and X-class solar flares. NOAA/SWPC forecasters estimate there is 65% chance for an M-class solar flare and 10% chance for an X-class solar flare.
