Welcome!

This blog provides commentary on interesting geological events occurring around the world in the context of my own work. This work is, broadly, geological fluid dynamics. The events that I highlight here are those that resonate with my professional life and ideas, and my goal is to interpret them in the context of ideas I've developed in my research. The blog does not represent any particular research agenda. It is written on a personal basis and does not seek to represent the University of Illinois, where I am a professor of geology and physics. Enjoy Geology in Motion! I would be glad to be alerted to geologic events of interest to post here! I hope that this blog can provide current event materials that will make geology come alive.

New coronal hole in the solar atmosphere, alert for aurora possibilities

Just saw a notice on Spaceweather.com that a large hole in the solar atmosphere is turning toward Earth. It is expected to blast us with a very high-velocity (700 km/second!!) stream of solar wind, arriving on June 16th, and possibly sparking G1-class geomagnetic storms. Could be interesting auroras particularly in the southern hemisphere because of the autumn darkness.
