Joint US-EISCAT Incoherent Scatter Radar School is taking place. Tonight, starting from 2200hrs UTC, the students will run their own radar experiments on this radar, split into six groups having the radar for two hours each. Leading up to these experiments, this afternoon the groups will meet and discuss what kind of experiments they want to run, and as part of their training, they will write a brief experiment proposal to apply for radar time. Exciting times ahead!
