INFO FROM SIDC - RWC BELGIUM 2018 May 22 13:03UTC

Solar activity was at low levels. Catania sunspot group 82 (NOAA AR 2710)
produced one B2.8 flare peaking at 05:07 UT today. 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 be at low levels with some probability for C-class
flares.
The solar wind speed remained below 400 km/s over the past 24 hrs.
Interplanetary magnetic field magnitude remained below 5 nT till 11:00 UT
today (recorded by ACE). Later interplanetray magnetic filed magnitude
gradually increased till 9 nT, simutaniously Bz component decreased from -2
nT till -5 nT. Solar wind parameters variations may increase from now due
to the expected influence of the recurrent positive polarity northern polar
coronal hole. Solar wind speeds may increase till about 500 km/s later
today or tomorrow (accodring to STEREO data). Geomagnetic conditions have
been quiet over the past 24 hrs. Unsettled geomagnetic conditions can be
expected today and tomorrow. Isolated episodes of active conditions are
also not excluded.
