Katelynn Greer is currently working as an Assistant Research Physicist at the Space Sciences Laboratory at the University of California- Berkeley, working with Tom Immel and Scott England. She studied at the University of Colorado at Boulder in the department of Aerospace Engineering Sciences where she earned her BS (2007) and MS (2009).
In The Conversation newsletter, scientists Delores Knipp and Brett Carter explore the significance of severe geomagnetic storm events and their impact on communications technology through descriptive historical accounts.
If you have visited the High Altitude Observatory, you may recall seeing the Maunder’s original butterfly diagram. The chart resembles three butterflies traveling west. Drawn by Annie S.D. Maunder and E. Walter Maunder, it demonstrated for the first time the movement of sunspot emergence from the poles toward the equator over the sun's 11-year cycle.
We study UV spectra obtained with the SO82-B slit spectrograph on board SKYLAB to estimate the fine structure splitting of the Cl-like 3p43d4D5/2 and 3p43d4D7/2 levels of Fe X.
The key elements of the Babcock-Leighton dynamos are the generation of poloidal field through decay and dispersal of tilted bipolar active regions and the generation of toroidal field through the observed differential rotation.
This paper investigates a possible physical mechanism of the observed dayside high-latitude upper thermospheric wind using numerical simulations from the coupled magnetosphere-ionosphere-thermosphere (CMIT) model.
