Solar activity was at low levels. Region 1236 (N17E58) produced a C7/1n flare at 16/1022Z with weak radio emissions in the 2695MHz to 15.4 GHz range, including a 130 sfu 10cm burst. The region showed little change over the past 24 hours. Region 1234 (S16W29) produced low-level B-class activity during the period. The region showed modest growth in spot count. Two low-level C-class x-ray events were observed from a region behind the east limb near S17. These events most likely originated from old Region 1223 (S17, L=130). A 10 degree eruptive filament, centered near S23W35, was observed lifting off just SW of Region 1234. Filament movement was first observed on SDO/AIA 193 imagery at 16/1426Z with a subsequent narrow CME off the SW limb, first observed in SOHO LASCO C2 imagery at 16/1612Z. Initial plane-of-sky velocity was estimated at 190 km/s. This slow CME does not appear to be Earth-directed.

Solar activity is expected to be low with a chance for M-class events all three days of the period (17 - 19 June).

The geomagnetic field was quiet to unsettled. Solar wind velocities were steady at about 450 km/s through 16/1500Z when a slight increase to about 480 km/s was observed. Coupled with the wind increase were slight rises in temperature and density, along with a general increase in low energy particles.

The geomagnetic field is expected to be at quiet to unsettled conditions with isolated active periods on day one and two (17 - 18 June). The forecasted increase in activity is in response to possible effects of a glancing blow from the CME observed early on 14 June. By day three (19 June), field conditions are expected to return to mostly quiet levels.
