Bulletin
The Sun produced several small C-class flares, originating from NOAA AR 2146, AR 2149 and AR 2152. AR 2146 has now rotated around the West limb. No Earth-directed CMEs were detected. More C-class flares are expected, with a slight chance for M-class flares. Solar wind speed values ranges between 400 and 450 km/s. The magnitude of the interplanetary magnetic field remained relatively stable around 6 to 7 nT, while Bz is fluctuating between -6 and +6 nT. Geomagnetic conditions are unsettled to active and are expected remain so for the next 48 hours, due to the influence of the increased solar wind related to the equatorial coronal hole.
