It erupted from AR NOAA 0933 (Cat 9), situated on the western limb. More C-class flares are possible. The solar wind is slightly disturbed, but solar wind speed and the total B remain low such that quiet conditions are expected to persist. As the sun is rotating, a coronal hole becomes visible in the east, which may lead to disturbed geomagnetic conditions at the beginning of next week.
