Seeker, an American digital media network and content publisher, interviewed HAO's space scientist, Delores Knipp, in July 2019. The presentation is titled "How Earth's Magnetic Field Twists and Buckles During Solar Storms." Dr. Knipp uncovered a war mystery that is connected to a major solor storm event in July 1972.
Following its long history of solar eclipse field expeditions, the High Altitude Observatory currently has a team deployed in Cerro Tololo, Chile to conduct solar physics research. On July 2, a total solar eclipse will be visible in South America, fortuitously passing over the NSF's Cerro Tololo Inter-American Observatory.
Earthquake and tsunami are known to be the source of atmospheric gravity waves that can generate plasma ripples in the space. On March 11, 2011, a magnitude 9.0 earthquake occurred near the east coast of Honshu, Japan, unleashing a savage tsunami to strike offshore of Japan.
Deriving the strength and direction of the three-dimensional (3D) magnetic field in the solar atmosphere is fundamental for understanding its dynamics. Volume information on the magnetic field mostly relies on photospheric and/or chromospheric surface vector magnetic fields.
The NASA Global-scale Observations of the Limb and Disk (GOLD) ultraviolet spectrograph began imaging the Equatorial Ionization Anomaly (EIA), regions of the ionosphere with enhanced electron density north and south of the magnetic equator, in October 2018.
