Instrument: 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
