Product: Forecast Discussion Issued: 2013 Jun 10 0030 UTC Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center Solar Activity .24 hr Summary... Solar activity was at low levels due to a C3 flare at 09/0208 UTC from Region 1762 (S28, L=129) just behind the southwest limb. Slight decay was observed in the leader and trailing spots of Region 1765 (N08W36, Dai/beta). New Region 1767 (S17E42, Bxo/beta) was numbered today. No Earth-directed coronal mass ejections (CMEs) were observed during the period. .Forecast... Solar activity is expected to be very low with a chance for C-class flares and a slight chance for an M-class (R1-Minor) flare for the forecast period (10-12 Jun). Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux at geosynchronous orbit was at moderate to high levels. The greater than 10 MeV proton flux at geosynchronous orbit was at background levels (Below S1-Minor). .Forecast... The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at moderate to high levels on days 1-2 (10-11 Jun) and decreasing to normal to moderate levels by day 3 (12 Jun). The greater than 10 MeV proton flux at geosynchronous orbit is expected to be at background levels. Solar Wind .24 hr Summary... Solar wind started the period near 380 km/s and increased to a maximum of 482 km/s at 09/0727 UTC, but has since declined to end of period values near 355 km/s. Total field measurement varied from 1 nT to 6 nT while the Bz component was variable between +/- 6 nT. Phi angle was positive (away) from 09/0000 UTC till approximately 09/0430 UTC when it became mostly negative (towards) until 09/1810 UTC when it switched to a positive sector once again. .Forecast... Solar wind is expected to be at nominal levels for the forecast period (10-12 Jun). Geospace .24 hr Summary... The geomagnetic field was at quiet to unsettled levels (Below G1-Minor). .Forecast... The geomagnetic field is expected to be at quiet to unsettled levels on day 1 (10 Jun). Mostly quiet conditions are expected on days 2-3 (11-12 Jun). swpc.noaa.gov/
