Im not home tonight nor do I have a ready computer to make a proper post about the northern lights; however, I can type and share information! Check this out from solarham.net: 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. Strong G3 level geomagnetic storming is now being observed at high latitudes. 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. Theres a lot of scientific data there but to summarize, the Earth is getting hammered with charged particles from the Sun. The northern lights may be visible over the coming hours as shock waves reverberate throughout the magnetic field. A Kp value of 7 remains likely overnight (see post from last night for explanation). Some clouds are moving though both regions but should break enough to see glimpses of sky. Clouds will increase toward dawn so be sure to get out and see what you can see!
