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 continued at very low levels. Region 2776 (S14W38, Hsx/alpha)remained quiescent. No Earth-directed CMEs were observed in available satellite imagery.
Solar activity is expected to be very low on 22-24 Oct.
Solar wind parameters were at nominal levels. Total field strength averaged near 7 nT, the Bz component saw a maximum southward deflection to -5 nT, wind speed was between 330-415 km/s, and the Phi angle was oriented predominantly in the negative sector.
Solar wind parameters are expected to see intermittent enhancements on 22-24 Oct due to the influence of several CH HSS.
The geomagnetic field was quiet to unsettled. .
The geomagnetic field is expected to be at quiet to active levels, with G1 (Minor) levels likely on 22-23 Oct, due to influences from a series of extensions from the northern crown CH HSS. Unsettled to active levels are expected on 24 Oct as CH HSS effects persist, yet begin to subside.
