BackForwardInstrument:  MUSE 

Instrument details
Acronym MUSE
Full name Monitor of Ultraviolet Solar Energy
Purpose To observe time variations of the UV solar radiation
Short description UV radiometer operating in five channels: 121.6 nm (H Lyman-alpha), 180 nm, 210 m, 260 nm and 280 nm, indicative of several processes in the solar chromosphere and photosphere
Background The channels in the unit of Nimbus-4 were slightly different from those on Nimbus-3: channels 210 and 280 nm replaced 160 and 200 nm, that did not work properly
Scanning Technique Sun pointing from a sunsynchronous orbit
Resolution N/A (full disk)
Coverage / Cycle Full disk in 50 s
Mass Power Data Rate
