• Irina Kitiashvili with the NASA Solar Cycle 25 Forecast

    Next solar cycle – Solar Cycle 25 – is expected to be the lowest in 200 years. The forecast for the next solar cycle says it will be the weakest of the last 200 years. The maximum of this next cycle – measured in terms of sunspot number, a standard measure of…

  • 5 Earth-directed CMEs, G3 – Strong geomagnetic storm

    A several degree long solar filament south of the Region 2741 disappeared by approximately 15:14 UTC on May 13, 2019. Initial analysis suggests an Earth-directed component is likely with this Coronal Mass Ejection (CME). This is the fifth Earth-directed CME since…

  • C4.8 solar flare erupts from AR 2736, full-halo CME produced

    A solar flare measuring C4.8 at its peak erupted from newly-emerged AR 2736 on March 20, 2019. The eruption started at 10:35, peaked at 11:18 and ended at 11:34 UTC. The region was also responsible for several B-class flares over the past 7 hours. The flare was…

  • Negative polarity CH HSS sparks geomagnetic storming

    An isolated, negative polarity Coronal Hole High Speed Stream (CH HSS) is affecting our planet on February 27 and 28, 2019, causing isolated periods of geomagnetic storming. Solar winds over the past 24 hours were indicative of an anticipated Solar Sector Boundary…
