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 was at moderate levels. Region 3815 (S28E15, Eso/beta-gamma) produced the only M-class flare of the period, a long duration M1.6/1F flare, at 07/0749 UTC. Regions 3806 (S08W67, Dsi/beta-gamma), 3808 (S09W58, Cao/beta) and 3813 (S25E03, Fki/beta-gamma) added some C-class flares, the largest being a C7.2/1f flare from Region 3806 at 07/2119 UTC. Region 3814 (N15E38, Cso-beta) was the only region to exhibit growth during the period, gaining a few peripheral spots. New Regions 3818 (S13W34, Cao/beta) and 3819 (S30E28, Cao/beta) were numbered this period. The remaining regions were degenerating and inactive. The CME associated with the M-class flare event, mentioned in the previous discussion, was analyzed and deemed to be heading well south of the ecliptic plane. No Earth-directed CMEs were observed in available satellite imagery.
R1-R2 (Minor-Moderate) radio blackout events are likely, with a slight chance for R3 (Strong) or greater events, on 08-10 Sep.
Solar wind parameters continued at background levels. Total field averaged near 8 nT, the Bz component observed only minor southward deflections to near -7 nT, and solar wind speeds dropped below 350 km/s by the end of the period. Phi was in a negative orientation.
Enhancements in the solar wind environment are expected on 08 Sep as a positive polarity CH HSS is anticipated to move into a geoeffective position. Elevated levels are expected to continue through 09 Sep before the HSS moves out of a geoeffective location by 10 Sep.
The geomagnetic field was at quiet and unsettled levels.
A positive polarity CH HSS is expected to move into a geoeffective position on 08 Sep, increasing conditions to quiet to unsettled levels, with active periods likely. The elevated conditions are expected to persist into 09 Sep. By 10 Sep, the HSS is expected to move out of its geoeffective position, allowing conditions to return to mostly quiet levels.
