A shock was detected in the solar wind data around 09:10 UTC on June 28. The interplanetary magnetic field jumped from 11 nT to 18 nT, the solar wind speed increased from 327 km/s to 371 km/s, and the solar wind density at the shock rose from 5 particles/cm3 to 17 particles/cm3. This shock is related to the arrival of an ICME, likely associated with a partial coronal mass ejection observed on the morning of June 25. Geomagnetic conditions are expected to be disturbed, with active to minor storm conditions possible depending on the Bz component.

Geomagnetic conditions reached moderate storm levels globally (Kp 6) between 09:00 UTC and 12:00 UTC on June 28, due to the ICME that arrived today. Locally, only unsettled conditions (K-Bel = 3) were observed over Belgium. Further active to moderate geomagnetic storm conditions may be possible in the next 24 hours.

Geomagnetic conditions reached severe storm levels globally (NOAA Kp 8-) between 12:00 and 15:00 UTC on June 28. Locally, moderate storm conditions were observed over Belgium (K-Bel=6) between 12:00 and 18:00 UTC on June 28. Geomagnetic conditions are expected to gradually decrease over the next several hours, with a chance of reaching minor to moderate storm levels if prolonged periods of negative Bz occur while the Earth remains under the influence of the ICME.
