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 very low. Region 2822 (N18W10, Dao/beta-delta) continued its slow decay, and produced only a few B-class enhancements. Region 2823 (S22E00, Hrx/alpha) also underwent decay and was inactive. Dimming was observed in SUVI 193 imagery near Region 2822 at approximately 13/1600 UTC. This event coincided with a B1 flare and appears to have an Earth-directed component, based on STEREO A COR 2 imagery. Further analysis/WSA Enlil modeling will occur as the relevant coronagraph imagery becomes available.
Very low solar activity is expected, with a chance for C-class flares 14-16 May, due primarily to the minor instability of Region 2822.
Solar wind conditions were indicative of weakening CME influences. Total field steadily decreased over the period from 14 nT to 5 nT while Bz was mostly in a northward orientation. Solar wind decreased from ~525-425 km/s. Phi was negative.
Nominal levels are expected to persist through 16 May.
Quiet levels were observed over the last 24 hours.
Quiet to unsettled conditions are expected on 14 May, and a return to primarily quiet conditions is expected on 15-16 May.
