  1. The ARRL Solar Report

    Solar activity remained at moderate levels earlier this week. There
    was an approximately 20-degree filament eruption on June 4 and a
    possibly related Coronal Mass Ejection (CME). The CME is unlikely to
    have an Earth-directed component, but analysis is in progress.

    The geomagnetic field is expected to be quiet to unsettled on June 7
    as High Speed Stream (HSS) activity continues. G1 (Minor) storm
    level...

  10. The ARRL Solar Report

    Solar activity reached moderate levels early this past week with
    several flares. An X1-class flare erupted mid-week, but activity has
    slowed down with the majority of the low-level C-class flares. A
    coronal mass ejection (CME) was observed on May 27 with a flare from
    Region AR4100.

    Modelling determined the CME to be well behind Earth's orbit. No
    other potentially Earth-directed CMEs were detected in...
