There are 6 active regions on the visible side of the solar disk. Only NOAA AR 12146 (in NE quadrant) has shown a significant growth in the past 24 hours. We expect it will push up solar activity to C-class flaring levels, though further growth in size, complexity and thus flaring levels cannot be excluded. Note also that flaring activity is observed from behind the NE solar limb.Quiet geomagnetic conditions are expected in the coming 3 days: there are no high speed wind streams expected from coronal holes, nor are there any new CMEs on the way to the Earth. The arrival yesterday (Aug 19) of the Aug 15 CME resulted in a Kp=6 episode. The Bz component of the IMF has now turned fully Northward, thereby ending the geomagnetic storm.
