Bulletin

Solar activity has been very low in the past 24 hours, with only a B4.1 flare in NOAA AR 1765 at 1018 UT (peak time), on June 9. This region is now classified as beta, but is still capable of producing C flares, which justifies the eruptive conditions foreseen for the next 48 hours. Geomagnetic conditions are currently unsettled to active at local and planetary levels. ACE observations show relatively strong variations of the Bz component of the interplanetary magnetic field, down to -10 nT early on June 10, but currently attenuating. A very small step in the solar wind speed around 0200 UT, associated with the beginning of this unsettled period, hints at the arrival of a very attenuated shock, possibly the eastern edge of the CME associated with the M flare of June 7. We expect mostly quiet conditions for the next 48 hours.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 020, basierend auf 11 Stationen.
