The Design and Performance of the Gondola Pointing System for the Sunrise II Balloon-Borne Stratospheric Solar Observatory

Schematic of the Sunrise Gondola
Friday, November 4, 2016

At one meter, the Sunrise Balloon-Borne Stratospheric Solar Observatory is the largest solar telescope to leave the earth. Its aim during its June 12 to June 17, 2013 flight was to study the magneto-convective processes of the sun at a resolution of better than 100 km.

Effects of Magnetospheric Lobe Cell Convection on Dayside Upper Thermospheric Winds at High Latitudes

Average ionospheric potential and DMSP F-16 ion drift observations
Tuesday, October 4, 2016

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.

Annie Maunder, A Pioneer of Solar Astronomy

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.
