Rapid Eye Mount telescope

The Rapid Eye Mount telescope (REM) is a fully automatic, 60 cm aperture telescope located at ESO's La Silla Observatory at 2,400 metres altitude on the edge of the Atacama Desert in Chile. The telescope's aim is to catch the afterglows of gamma-ray bursts (GRBs). REM is triggered by a signal from a high-energy satellite such as Swift and rapidly points to the detected location in the sky. It is operated for the Italian National Institute for Astrophysics since 2002.
