Solar activity continues to be very low with only few minor C-class flares in past 24h. NOAA AR 2259 produced the strongest one, a C1.3 flare with peak at 10:13 UT. An AR rotating now over the east limb may rise activity levels in the coming hours. Geomagnetic conditions are quiet and expected to remain so. There are a couple of small equatorial coronal holes that may cause the arrival of a fast speed stream to the Earth today or tomorrow and increase geomagnetic conditions (probably not more than active conditions).
