LIMB FLARES: The northwestern limb of the sun is crackling with M-class solar flares(M3.2, M1.6, M1.2). The source appears to be departing sunspot complex active region 11286. Coronal mass ejections (CMEs) emerging from the blast site are not Earth-directed. Nevertheless, these flares are having a minor effect on Earth as their radiation ionizes our planet's upper atmosphere.
