Bulletin

Solar activity was at very low levels. There are currently two sunspot groups on the solar disk: active region NOAA 2738, and a small, not yet numbered region located near N05W12 that started its development after 07UT. No earth-directed coronal mass ejections were observed over the last 24 hours. The greater than 10 MeV proton flux was at nominal values.

Solar activity is expected to remain at very low levels.

Solar wind speed gradually decreased from its initial 400 km/s to its current values just below 350 km/s (DSCOVR). Bz varied between -3 and +3 nT. The interplanetary magnetic field remained predominantly directed towards the Sun (negative sector). Quiet geomagnetic conditions were observed.

Quiet geomagnetic conditions are expected to continue, with a small chance on an isolated unsettled interval.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 012, gebaseerd op 15 stations.
