While solar radiation enables and sustains life on Earth, it also produces “space weather” that can profoundly impact different technologies, including telecommunications, satellite navigation, and the electric power grid. Solar flares can produce x-rays resulting in radio blackouts that block high-frequency radio waves.
Holly Gilbert, HAO director, informed our community of the heartbreaking news of the recent passing of Peter Fox. Peter was at HAO from 1991 to 2008. He was a Scientist until 1995, and Chief Computational Scientist from 1995 to 2008. While at HAO he wrote detailed technical schema that remains decades ahead of its time to this date.
The neutral winds in the Mesosphere and Lower Thermosphere (MLT) region have been observed at King Sejong Station, Antarctica using a meteor radar and a Fabry-Perot interferometer (FPI) simultaneously.
Kelvin waves are large scale wave that is important for Earth’s atmosphere. The Ultra-Fast Kelvin waves (UFKW) are a subset of the Kelvin waves that can propagate to the mesosphere and lower thermosphere (MLT) ~100km and above due to their high zonal phase speeds.
The bulk of the emission from the plasma called "transition region" plasma originates from structures energetically connected both to the chromosphere and corona.
