"Bad Boy" active region 1339 continues to flare. At 20:27 UT a solar flare peaked at X1.9. X-class flares are pretty massive and are major events that can trigger planet-wide radio blackouts and long-lasting radiation storms.

The location of this sunspot/active region is still not quiet Earth directed.
