About
This 1970 photograph shows the Skylab's Ultraviolet (UV) Spectrograph, an Apollo Telescope Mount instrument. Its telescope, with camera and TV capability, photographed the Sun in selected ultraviolet wavelengths. The spectrograph was used to record the spectrum of UV emissions, such as flares or filaments, from a small individual feature on the solar disc. Real-time TV was used by the crew to monitor the performance of the telescope, transmit to the ground, and record. The exposed films were retrieved by astronaut extravehicular activities. The Marshall Space Flight Center had program management responsibility for the development of the Skylab hardware and experiments. — NASA MSFC · 1970.
