Description

This structure contains an entrance window and two mirrors that guide the light of the Sun down the tower in an evacuated tube from which the air has been removed. With136 feet above ground, the building extends 228 feet below, so most of the building is in fact not visible. The telescope is used to study granulation, sunspots, faculae, weak magnetic field, filaments, and solar flares.
