Bulletin

Solar activity was at very low levels. Active region NOAA 2708 is currently the only sunspot group visible on the solar disk. The source region of the 3 May CME (farside) is about to rotate over the east limb. No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal levels.

Solar activity is expected to be at very low levels, with a slight chance on a C-class flare.

Earth is under the influence of the high speed stream (HSS) from an elongated negative polarity equatorial coronal hole (CH). Solar wind speed mostly undulated between 610 and 710 km/s (DSCOVR). Bz varied between -6 and +6 nT. The interplanetary magnetic field was mostly directed towards the Sun, with some "away" excursions from 07UT onwards. Mostly unsettled to active geomagnetic conditions were observed, with an isolated minor storming episode in the Kp index during the 21-24UT interval.

Quiet to active geomagnetic conditions are expected, with a chance on an isolated minor storming episode.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 015, gebaseerd op 23 stations.
