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 MLSO web page will be unavailable for a few days sometime between now and the end of August for computer upgrades. Thank you for your patience.
