Bülletään

Solar activity was at very low levels. The Sun is spotless. 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 remain at very low levels.

Solar wind became enhanced as the wind speed, initially steady at 420 km/s, started a gradual increase around 01UT to values near 500 km/s by the end of the period. Bz oscillated between -6 and +7 nT (DSCOVR). The interplanetary magnetic field (IMF) was mostly directed towards the Sun. A small negative equatorial coronal hole (CH) is transiting the central meridian.

The geomagnetic field was at quiet to unsettled levels and is expected to remain so during the next few days. An active episode is possible from the moderate speed wind streams associated with the observed CHs.
