The 150-foot solar tower telescope at Mount Wilson Observatory was constructed to study the position, strength, and polarity of magnetic fields on the Sun. These measurements have been made since 1912, a record that allows long-term changes related to the 11-year sunspot cycle to be tracked.
Construction on the tower began in 1909.
The telescope is constructed vertically to take advantage of the steadier air above the Sun-baked ground.
The Solar Cycle Program is a long-term project at UCLA that uses this facility to provide high-quality maps of the Sun's activity on a daily basis.
