Auringon aktiivisuus

  • Edellinen vuorokausi

    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.

  • Lähipäivien ennuste

    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.

Aurinkotuuli

  • Edellinen vuorokausi

    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.

  • Lähipäivien ennuste

    Nominal levels are expected to persist through 16 May.

Geomagneettinen kenttä

  • Edellinen vuorokausi

    Quiet levels were observed over the last 24 hours.

  • Lähipäivien ennuste

    Quiet to unsettled conditions are expected on 14 May, and a return to primarily quiet conditions is expected on 15-16 May.
