Mauna Loa Solar Observatory (MLSO) acquires unique observations of the Sun’s atmosphere to support NCAR’s goal to address critical gaps in understanding the Sun-Earth system and to provide observations to reduce damage and disruption from space weather hazards.

The UCoMP instrument on the MLSO spar.

UPDATE: Solar panels will be installed this month (May) at MLSO to restore full power to the observatory. We expect to be fully operational in June. Most significantly, this means the return of UCoMP data! Stay tuned. (image shows the UCoMP instrument on the MLSO spar)
