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 returned to low levels with only C-class flares observed. Region 3961 (S10W76, Eki/beta-gamma) was responsible for the majority of the flares, as well as the largest: a C6.5 flare at 25/0022 UTC. This region appeared to continue its decaying trend as it rotated onto the west limb, but foreshortening was making accurate analysis difficult. Region 3971 (N13W63, Dac/beta-gamma) was foreshortened as well, but did appear to continue to develop additional spots as it approached the west limb. New region 3973 (N13W02, Dao/beta) developed during the period and was numbered. The remaining regions were either in decay or remained unchanged. No Earth-directed CMEs were observed. .
There is a chance of M-class flares (R1-R2, Minor-Moderate), with a slight chance for an X-class flare (R3, Strong), on 26-28 Jan. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux was at normal to moderate levels. The greater than 10 MeV proton flux was at background levels. .
Solar wind parameters were trending background nominal levels. Solar wind speeds averaged near 400 km/s for the majority of the reporting period. Total field settled in near 3 nT, while the Bz component weakly fluctuated between +/-4 nT. Phi angle remained predominantly negative.
An enhanced solar wind environment is still possible on 26 Jan if the anticipated passing of a CME that left the Sun on 22 Jan materializes. A transition back to nominal conditions is likely on 27 Jan if the aforementioned enhancements occur.
The geomagnetic field was quiet.
There is still a chance for G1 (Minor) storming conditions early on 26 Jan if CME that left the Sun on 22 Jan does eventually arrive. Mostly quiet conditions are expected to return for 27-28 Jan.
