A fast forward shock was observed in the solar wind parameters at 18:35 UTC on July 16. The solar wind velocity increased from 376 km/s to 434 km/s. The interplanetary magnetic field jumped from 7 nT to 13 nT. The solar wind speed reached a maximum of around 500km/s before then oscillating around 440 km/s. The magnetic field reached a peak value of 15 nT with a minimum negative Bz of -9nT. This resulted in minor geomagnetic storms (NOAA Kp=5). It is not clear which of the events from the past days may be responsible for this shock arrival. Further enhancements continue to be possible from further expected ICME arrivals.

Two halo coronal mass ejections (CMEs) were observed in LASCO/C2 coronagraph data at 13:48 UTC on July 16 and 01:54 UTC on July 17. Both of these are deemed to be back-sided with no expected impact at Earth.
