A shock was detected in the solar wind data around 13:30 UTC on August 17. The interplanetary magnetic field jumped from 7 nT to 17 nT, the solar wind speed increased from 324 km/s to 430 km/s, and the solar wind density at the shock rose from 2 particles/cm3 to 12 particles/cm3. This shock is related to the arrival of an ICME, likely associated with a partial coronal mass ejection observed on August 14. Geomagnetic conditions are expected to be disturbed, with active to minor storm conditions possible depending on the Bz component.

Geomagnetic conditions have reached major storm levels globally (NOAA Kp 7-) and moderate storm levels locally (K BEL 6) since 15:00 UTC on August 17. This is most likely the result of an interplanetary coronal mass ejection (ICME) arrival, associated with tha partial halo CME detected on August 14. The Bz component is currently at -4 nT, having reached -20 nT around 16:20 UTC on August 17. Geomagnetic conditions may remain at least at minor storm levels in the next 24 hours.
