Solar activity is low, NOAA AR 2389 produced a C1.1 flare with peak at 12:34 UT on July 26. More C-class flares can be expected.

Geomagnetic conditions have reached active levels at planetary level (Kp = 4) due the mild influence of the solar wind from a small equatorial coronal hole. Unsettled to active conditions can be expected in the coming hours.
