Auringon aktiivisuus

  • Edellinen vuorokausi

    Solar activity decreased to low levels, with only C-class flare activity observed. Region 4140 (S15E46, Cao/beta) produced the majority of the C-class activity, the largest being a C9.0 flare at 13/0402 UTC. Regions 4138 (N29W39, Dao/beta) and 4139 (N22W04, Dai/beta) exhibited minor growth, while the remaining regions were mostly stable or in decay. No Earth-directed CMEs were detected in available coronagraph imagery. .

  • Lähipäivien ennuste

    Solar activity is expected to be predominately low over 14-16 Jul, with a chance for M-class (R1-R2/Minor-Moderate) flare activity. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux reached moderate levels, and the greater than 10 MeV proton flux was at background levels. .

Aurinkotuuli

  • Edellinen vuorokausi

    Solar wind parameters continued to reflect positive polarity CH HSS influence. Total magnetic field strength reached 12 nT, and the Bz component briefly reached as far south as -10 nT. Solar wind speeds peaked near 725 km/s at 13/0750 UTC before gradually decreasing to around 575 km/s by the end of the period. The phi angle remained positive through most of the period.

  • Lähipäivien ennuste

    Elevated solar wind parameters are expected to persist over 14-16 Jul due to continued positive polarity CH HSS influence.

Geomagneettinen kenttä

  • Edellinen vuorokausi

    The geomagnetic field reached G1 (Minor) storm levels due to positive polarity CH HSS influence.

  • Lähipäivien ennuste

    Positive polarity CH HSS influence is expected to persist over 14-16 Jul. The geomagnetic field is likely to reach active levels on 14 Jul, with a chance for G1 (Minor) storming, followed by quiet to unsettled conditions and a chance for active periods on 15-16 Jul.
