ISR School assembled in the main auditorium of the visitor centre of the Arecibo Observatory to begin the radar school.
EISCAT Scientific Association, Craig Heinselman, welcomed the participants and pointed out how important these schools are in terms of making connections between all participants, learners and instructors alike, from which often spring life-long collaborations and even friendships.
Arecibo Observatory welcomed the participants and discussed a few practicalities and peculiarities related to the operations of the observatory. These include the strict radio silence, and also the need to keep light pollution as low as possible in order not to disturb optical experiments at nighttime.
Yesterday, we mentioned already the feed system suspended above the main reflector. Here one can also see a few extra antennae at the centre of the reflector, which are the ionospheric heater.
