A shock was detected in the solar wind data (ACE and DSCOVR) at 14:45 UTC on October 10. The interplanetary magnetic field jumped from 9 nT to 25 nT, with the Bz component changing from 6 nT to -25 nT. The solar wind speed jumped from 460 km/s to around 790 km/s. The solar wind density at the shock jumped from 9 ppcc to around 25 ppcc (DSCOVER). The shock is probably related to an expected interplanetary coronal mass ejection (ICME) arrival, associated with the CME observed at 02:30 UTC on October 09. Geomagnetic conditions are currently at unsettled levels globally and locally (NOAA Kp 3 and K BEL 3) but are expected to increase. Further monitoring and analysis are ongoing.

The global geomagnetic conditions have now reached major storm levels (near real-time NOAA Kp 7). The geomagnetic conditions locally have reached minor storm levels (K BEL 5). These geomagnetic storms are the result of the interplanetary coronal mass ejection (ICME) arrival, associated with the CME observed at 02:30 UTC on October 09. Geomagnetic conditions are expected to increase further over the next hours, potentially to severe storm levels (NOAA Kp 8). Further monitoring of the event is ongoing.
