Galactic and Extragalactic High Velocity Clouds Workshop

This will be a small workshop where scientists who are interested in Galactic and extragalactic High Velocity Clouds (HVCs) will gather for lively discussions of the latest observations, computational models and theoretical explanations.

Update:   We have cancelled the workshop.     Several speakers were unable to travel, owing to their institutions' concerns about the corona virus, and additional  moratoria were anticipated.

Previous Update:  We are monitoring the coronavirus closely.    No cases have been reported near Athens, Georgia, where the meeting will be held.    The US Center for Disease Control and Prevention in only 75 miles from Athens.    Although we are hoping that the coronavirus will be under control long before the workshop, we are also taking stock of the advisories from various space agencies in order to estimate their likely effect on workshop attendance.
