About the Mauna Loa Solar Observatory

The Mauna Loa Solar Observatory (MLSO) occupies part of the NOAA Mauna Loa research site located on the flank of Mauna Loa at an elevation of 3440 meters on the island of Hawaii. It is operated by the High Altitude Observatory, a division of the National Center for Atmospheric Research, which is located in Boulder, Colorado.

Responses of the Thermosphere and Ionosphere System to Concurrent Solar Flares and Geomagnetic Storms

Space storms that go off-scale

Terrestrial and space weather storm scales have a common shortcoming: The scales end at “5.” Nature of course doesn’t know this and sometimes produces a disturbance that is simply off the charts.
