Bülletään

The Sun was spotless. Solar activity was at very low levels and is expected to remain so.

The greater than 10 MeV proton flux was at nominal levels and is expected to remain so. The greater than 2 MeV electron flux reached moderate levels, with a maximum of 4801 pfu at 14:40UT. Despite showing signs of weakening, the electron flux has a chance to reach moderate levels again.

No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery.

The earth environment entered a sector with more enhanced solar wind, after the direction of the interplanetary magnetic field (phi angle) switched from predominantly towards the Sun (negative sector) to away from the Sun (positive sector) at 14:50UT (DSCOVR). Solar wind speed gradually increased from 280 km/s to 340 km/s around 07:30UT, ending the period with values around 330 km/s. Bz was mostly negative, varying between -5 nT (around 06:00UT) and +6 nT (around 10:30UT).

Geomagnetic activity was at quiet levels, with the estimated Kp index recording an isolated unsettled episode during the 06-09UT interval. Geomagnetic activity is expected to be mostly quiet, with an isolated unsettled interval possible.
