Tällä sivulla voit lukea NOAA SWPC:n julkaisemat kommentit auringon havaitusta aktiivisuudesta edellisen vuorokauden kohdalta sekä muutaman seuraavan vuorokauden kattavan ennusteen. Uusin alkuperäinen julkaisu on luettavissa täällä. Tiedot päivittyvät kaksi kertaa vuorokaudessa.
Solar activity increased to low levels this period. Region 4503 (S17W60, Cao/beta) produced a long duration C4.1/Sf at 14/0701 UTC. Associated with this flare was a Type II radio sweep with an estimated velocity of 671 km/s. The largest region on the disk, Region 4507 (N04E07, Dsi/beta-gamma) produced a pair of B9.2 events at 13/1835 UTC and 14/0552 UTC. This region continued to show some weak development in the leader portion of the group. Region 4508 (N11E34, Cao/beta) produced an impulsive C1.5 flare at 14/0953 UTC. Region 4506 (N11W10, Bxo/beta) produced an impulsive C1.1/Sf flare at 14/1142 UTC. The remaining active regions were either largely stable or in decay. At about 14/0332 UTC, a 25 degree long U-shaped filament centered near S16E22, lifted off the disk. Surge material was observed moving in a westward direction across the disk. However, no Earth-directed CMEs were observed in available coronagraph imagery. .
Isolated C-class flares, with a slight chance (15%) for R1-R2 (Minor-Moderate) radio blackouts, are likely through 16 Aug. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux at geosynchronous orbit was at moderate levels. The greater than 10 MeV proton flux at geosynchronous orbit remained at background levels. .
Solar wind parameters reflected an ambient-like environment. Total field was at 3-8 nT, while the Bz component varied between +/-6 nT. Solar wind speeds gradually decayed from about 400 km/s to near 350 km/s. The phi angle was predominantly in a positive solar sector.
Early on 14 Aug, enhancements are anticipated with the arrival of a corotating interaction region (CIR) ahead of a +CH HSS. Enhanced solar wind conditions are likely to then persist through 16 Aug under +CH HSS influences.
Geomagnetic field activity was at quiet to unsettled conditions.
On 14-15 Aug, unsettled to active levels are expected in response to +CH HSS influences with a slight chance for G1 (Minor) geomagnetic storming or greater. 16 Aug is anticipated to return to mostly unsettled levels as CH HSS influences wane.
