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 very low levels. Region 2797 (S18E14, Hax/alpha) was stable and inactive. Region 2798 (S16E28, Axx/alpha) decayed and was also void of significant activity. A new spot group emerged in the NW portion on the disk. We await further observations from the SOON analysts before assigning a region number. No Earth-directed CMEs were observed during the period.
Solar activity is expected to remain at very low levels, with a slight chance for C-class activity, on 22-24 Jan.
Solar wind parameters were at nominal levels. Total magnetic field strength was at or below 5 nT while the Bz component varied between +/-2 nT. Wind speed averaged around 300 km/s. Phi was variable.
A nominal solar wind environment is expected for the next three days (22-24 Jan).
The geomagnetic field was quiet. .
Mostly quiet conditions are anticipated through for 22-24 Jan.
