INFO FROM SIDC - RWC BELGIUM 2017 Oct 18 12:30UTC

Returning NOAA region 2682 (behind the East limb) produced a long duration
B2.3 flare peaking around 10:30 UT on October 18. The chance for a C flare
in the next 24 hours is estimated at 35%. NOAA 2682 erupted several times
over the past 24 hours. Though data gaps in STEREO A imagery prevented to
see the exact onset of some eruptions on the backside of the Sun, the
events caused CMEs which were observed by LASCO C2 and C3. The two most
significant CMEs (first seen in LASCO C2 images at 5:48 and 6:36 UT,
respectively) were both bright and fast and extended from the northeast to
the southeast, with a core towards the northeast. Since these are backside
events, these CMEs will not be geoeffective. The greater than 10 MeV proton
flux was at nominal levels.
Solar wind speed measured by DSCOVR decreased from about 475 to about 390
km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) was
predominantlty directed away from the Sun and its magnitude ranged between
about 0 and 4 nT. Quiet geomagnetic conditions (K Dourbes between 1 and 2;
NOAA Kp between 1 and 2) were registered in the past 24 hours. Quiet to
unsettled geomagnetic levels are expected on October 18, 19 and 20.
