The anticipated coronal mass ejection (CME) generated by the X1.6 solar flare on September 10th swept past Earth at 15:55 UTC. Solar Wind speeds as measured by the ACE spacecraft increased from 433.2 km/s, to 671.8 km/s. A Geomagnetic Sudden Impulse measuring 43 nT was detected by the ground based magnetometer in Boulder, Colorado. Moderate G2 level geomagnetic storming is now being observed at high latitudes. Strong G3 level storming will remain possible as we head into tonight. More to follow.
UPDATE: Solar wind speeds have picked up considerably and is now nearing 800 km/s. The Bz component of the interplanetary magnetic field (IMF) was tipped south, but has since turned back north. More fluctuations are to be expected during the next several hours. Visual aurora will be likely across northern Europe and Scandinavia, and if conditions hold our for a few more hours, Canada and the northern tier USA could see some activity as well. On the HAM Radio front, 6 meters (50mhz) is now alive with aurora signals as radio amateurs at higher latitudes point their antennas to the north and make radio contacts via the auroral curtain.
