ROTSE IIIb enclosure

The ROTSE IIIb telescope is inside this enclosure on McDonald Observatory's Mt. Fowlkes, not far from the much larger Hobby-Eberly Telescope. ROTSE, the Robotic Optical Transient Search Experiment, headquarters at The University of Michigan, has placed telescopes in four locations on Earth to cover the entire sky in search of gamma-ray bursts.
