Bülletään

Solar activity was at very low levels during the period. The visible solar disk is spotless. A bright faculae field rotated over the east limb. No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10MeV proton flux was at nominal levels.

Quiet flaring conditions are expected.

The earth environment remained under the influence of the high speed stream (HSS) from a positive polarity coronal hole (CH). Wind speeds gradually increased from an initial value near 560 km/s to about 700 km/s by 04UT, then decreased again to 600 km/s by the end of the period. Bz oscillated between -6 and +5 nT. The interplanetary magnetic field was directed away from the Sun.

The geomagnetic field was at quiet to unsettled levels, with an active episode during the 21-24UT interval recorded by both Dourbes and in Kp. Mostly quiet to unsettled geomagnetic conditions are expected, with a chance on another active episode as the influence of the CH HSS is expected to gradually subside over the next 1-2 days.
