Bülletään

The visible solar disk has been devoid of sunspots. Solar activity was at very low levels and is expected to remain so.

The greater than 10 MeV proton flux and the greater than 2 MeV electron flux were at nominal values and are expected to remain so.

No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery over the last 48 hours. An extension of the southern polar coronal hole is transiting the central meridian.

Solar wind speed undulated between mostly 400 and 450 km/s, then decreased after 05UT to its current values around 365 km/s (DSCOVR). Bz varied between -3 and +4 nT, being mostly negative between 18 and 05UT. The direction of the interplanetary magnetic field (phi angle) was in a predominantly sunward orientation (negative sector).

Geomagnetic activity was at quiet levels. Geomagnetic conditions are expected to be quiet to unsettled during the next few days.
