Sonnenaktivität

24h Zusammenfassung

Solar activity remained at low levels with most of the C-level activity originated from Region 4465 (N09E54, Dsi/beta-gamma), including the largest flare of the day; a C4.5/Sf observed at 09/0423 UTC. There are currently 8 numbered sunspot regions on the disk, with the inclusion of newly numbered Region 4466 (N06W16, Bxo/beta). Departed Region 4455 (N15, L=092) continued to produced some weak C-class flares, including a C3.2 at 09/0700 UTC. A Type-II radio sweep was observed by two RSTN stations at 09/1557 UTC, with estimated velocity of 917 km/s, likely associated with C-class flaring from Region 4463. The plage Region 4461 (S21W23, L=11) also produced some of the C-flares of the period, including a C2.3/1F (113 mil) at 09/1918 UTC. Some CME activity was observed in the coronagraph imagery during the period. One CME first observed at the NE quadrant of LASCO/C2 around 09/1630 UTC which was associated with an eruption near (and south of) Region 4463 (N16E10, Hsx/alpha). Preliminary analysis suggest glancing effects near-Earth on 14 June.

Vorhersage

Solar activity is likely to be moderate with a slight chance for an X-class flares through 12 Jun, mainly due to the flare potential of Regions 4464 (S12E11, Ehi/beta) and 4465.

Energiereiche Teilchen

24h Zusammenfassung

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels with a peak flux of 4,259 pfu at 09/1525 UTC. The greater than 10 MeV proton flux remained at background levels during the period.

Vorhersage

The greater than 2 MeV electron flux levels at geosynchronous orbit are likely to continue reaching high levels through 10 June, returning to moderate levels on 11-12 June. The greater than 10 MeV proton flux has a slight chance of crossing threshold through 12 Jun.

Sonnenwind

24h Zusammenfassung

Solar wind speed suggested the passage of a weak transient starting near 09/0950 UTC, with an increase of the total IMF from 5nT to 10 nT and the Bz component turning predominately south until about 09/1500 UTC. Another period of southward Bz component occurred between 09/1635-2000 UTC, reaching -8 nT at 09/1810 UTC. The transient also resulted in an increased density and temperature. Solar wind speed remained oscillating around 450 km/s during the period. The Phi angle remained mostly in the positive sector during the day.

Vorhersage

Background solar wind conditions are expected to be restored by 11 June, and a -CH HSS is anticipated to become geoeffective on 12 June, disturbing the near-Earth solar wind parameters.

Geospace

24h Zusammenfassung

The geomagnetic field has been at quiet to unsettled levels for the past 24 hours.

Vorhersage

The geomagnetic field is expected to be at quiet to active levels on 10 and 12 June, with a day of quiet to unsettled levels in between (11 Jun).
