The Sun Online and solar activity. August 31, 2014

A handful of C-class flares were observed, with NOAA AR 2149 and AR 2152 as source regions. NOAA AR 2152 has grown in size and complexity and has developed to a beta-gamma region. More C-class flares are expected, with a slight chance for an M-class flare. No Earth-directed CMEs were visible in
coronographic images.
The solar wind is under influence of a coronal hole (CH) high speed stream (HSS). The solar wind speed, as observed by ACE, reached values between 400 and 450 km/s. The magnetic field is relatively stable around 6 to 7 nT, with a fluctuating Bz. Geomagnetic conditions are unsettled to active and are expected remain so for the next few hours, until quiet conditions
