INFO FROM SIDC - RWC BELGIUM 2017 Jul 26 12:30UTC

Solar activity was at very low levels during the period. Sunspot region
NOAA 2668 is decaying and barely visible. No earth-directed coronal mass
ejections (CMEs) were observed in available coronagraphic imagery. The
greater than 10 MeV proton flux reached a maximum of about 2 pfu (i.e.
below the 10 pfu event threshold) around 21-22UT, and is now gradually
declining.

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 570 km/s to about 660 km/s by 03UT,
then decreased to 590 km/s by the end of the period (DSCOVR). Bz oscillated
between -5 and +7 nT. The interplanetary magnetic field was mostly directed
away from the Sun, with a "towards" sector during the 14-22UT interval. 
 
The geomagnetic field was at quiet to unsettled levels, with an active
episode during the 06-09UT interval recorded by both Dourbes and in Kp.
Mostly quiet to unsettled geomagnetic conditions are expected, with a
chance on another active episode under the persistent influence of the CH
HSS.
