No no no ... there was a slight CME but we are clear after today ... per solorham.com
“ Storm in Progress: The minor (G1) geomagnetic storm threshold was reached at 03:59 UTC (Jul 23).
The DSCOVR spacecraft is detecting a shock passage that is likely related to the faint halo CME observed leaving the Sun on July 21st. The solar wind speed looks to be nearing 700 km/s and the Bz component of the interplanetary magnetic field (IMF) is trending south for now. An impact to Earth's geomagnetic field should take place within the next 45 minutes. A geomagnetic storm warning will be in effect. Aurora sky watchers at higher latitudes should be alert.
Update: The CME reached Earth just before 03:00 UTC with a geomagnetic sudden impulse recorded by the Boulder, CO magnetometer.
SUMMARY: Geomagnetic Sudden Impulse
Observed: 2022 Jul 23 0259 UTC
Deviation: 103 nT
Station: MEA
