Solar activity was at low levels. A C1 x-ray event was observed at 13/0055Z from an area of enhanced brightening on the east limb near N20. Region 1234 (S16E07) remained the only spotted region on the disk. The region produced a few B-class events, the largest a B9 x-ray event at 13/0616Z. Region 1234 indicated little change over the past 24 hours and remained a simple B-type, bi-polar group. A partial halo CME was observed lifting off the SE limb, first observed in C2 SOHO LASCO imagery at 13/0424Z, and later in C3 imagery at 13/0454Z. The plane-of-sky velocity was estimated at near 600 km/s. The CME appeared to originate from a bright area of plage centered near old Region 1223 (S17, L=125), first viewed in STEREO-B EUVI imagery at 13/0355Z as an area of northward surging.

Solar activity is expected to be very low for the next three days (14 - 16 June) with a chance for an isolated C-class flare.

The geomagnetic field was at quiet to unsettled levels. ACE solar wind data indicated the continued presence of a coronal hole high speed stream (CH HSS) with wind speeds averaging about 450 km/s. The greater than 10 MeV proton flux at geosynchronous orbit remained enhanced with a maximum flux reading of 4.8 pfu at 13/1010Z.

The geomagnetic field is expected to be at quiet to unsettled levels for day one (14 June) with a chance for active levels due to continued CH HSS effects. Activity is expected to decrease to quiet levels on days two and three (15 - 16 June) as the CH HSS subsides. The greater than 10 MeV protons are expected to remain enhanced through 14 June, returning to background levels by 15 June.
