No proton events are expected at geosynchronous orbit. The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 13-14 Jul, 24-27 Jul, and 06-08 Aug due to the anticipated influence of multiple, recurrent coronal holes. Normal to moderate levels are likely throughout the remainder of the outlook period. Geomagnetic field activity is expected to range from quiet to active levels. Active levels are likely over 13-14 Jul, 16 Jul due to potential CME influence and again on 22 Jul, 01 Aug, And 04-05 Aug due to anticipated coronal hole influence. Unsettled level are likely on 15 Jul, 23 Jul, 02 Aug, and 06 Aug. The remainder of the outlook period is likely to be at mostly quiet levels.
