Educational outreach is an important and rewarding part of an observer’s job at the Mauna Loa Solar Observatory (MLSO) site located on the flanks of Mauna Loa Mountain at an elevation of 3440 meters in the U.S. state of Hawai’i.

On the responses of mesosphere and lower thermosphere temperatures to geomagnetic storms at low and middle latitudes

Temporal Variations of Kp
Friday, September 14, 2018

Observations from lidars and satellites have shown that large temperature increases and decreases occur in the middle and low latitudes of the mesosphere and lower thermosphere (MLT) region during geomagnetic storms.

Evolution of the Global Solar Magnetic Field over 4 Solar Cycles: Use of the McIntosh Archive

Butterfly-type plots of all of the McA data
Thursday, July 26, 2018

The McIntosh Archive consists of a set of hand-drawn solar Carrington maps created by Patrick McIntosh from 1964 to 2009. McIntosh used mainly H, He-I 10830Å and photospheric magnetic measurements from both ground-based and NASA satellite observations.
