INFO FROM SIDC - RWC BELGIUM 2017 Jul 20 12:30UTC

A C1.2 flare peaking at 00:02UT was recorded off the SouthWest Solar limb,
apparently still related to NOAA region 2665, which is by now already well
past the limb.
With no spotted regions on disk the probability for C flares is very low
over the next days.
SDO/AIA 304 shows a filament eruption in the Southern hemisphere from
03:13UT onwards. There are no significant related signatures of this event
in coronagraph data, and it is thus expected not to influence Earth.
Proton flux levels are at background values and are expected to remain so.

Solar wind was nominal for most of the period with solar wind speed
declining to values around 380 km/s and total magnetic field mostly under
4nT. The magnetic field phi angle switched back and forth three times as
some expected sector boundary crossings occurred. The phi angle now
indicates outward magnetic field orientation. Over the past hours,
temperature as well as total magnetic field have been rising (to around 8nT
presently) which could mark the first signs of the influence of the
extension of the positive polarity northern polar coronal hole.
Under the influence of the extension of the northern polar coronal hole
solar wind speed may increase over the next few days.
Geomagnetic conditions were quiet (local K Dourbes and NOAA Kp 1-2) and are
expected to become quiet to unsettled with possibly some isolated active
periods depending on the strength of the expected coronal hole influence.
