Early December Propagation of the Gemini South Laser

This image showing the propagation of the Gemini South laser guide star system is dedicated to the memory of Vincent Fesquet. Vincent worked tirelessly to make the Gemini South laser guide star system work efficiently and reliably. Leave your memories of Vincent at: www.gemini.edu/staff/vfesquet

Special thanks to the W.M. Keck Observatory and Pete Tucker for the extra assistance necessary to make this laser propagation possible in early December 2013.
