CME Impact #1 / Minor Storm Observed
The first of two coronal mass ejections swept past Earth on Thursday evening. The incoming plasma cloud, stemming from an M4.5 eruption on September 9th, reached our planet at 23:46 UTC. A geomagnetic sudden impulse measuring 33 nT was detected by the ground based magnetometer in Boulder, Colorado. Solar wind speeds reached near 500 km/s and the Bz component of the interplanetary magnetic field (IMF) continues to fluctuate. The impact resulted in a brief geomagnetic storm at high latitudes. A reminder that a larger and faster moving CME trailing behind the first once is expected to sweep past Earth within the next 6-12 hours.
