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.

On the Connection between Propagating Solar Coronal Disturbances and Chromospheric Footpoints

SDO/AIA 171Å sub-fields
Wednesday, September 14, 2016

The Interface Region Imaging Spectrograph (IRIS) provides an unparalleled opportunity to explore the (thermal) interface between the chromosphere, transition region, and the coronal plasma observed by the Atmospheric Imaging Assembly (AIA) of the Solar Dynamics Observatory (SDO).

1999 total eclipse

On August 21, 2017, Paul Bryans and his team of scientists will be ready to aim a spectrometer at the sun during total eclipse in an effort to detect the effect of magnetism on certain wavelengths of infrared light emitted by the corona.

Comet ISON's missing light

Tuesday, May 24, 2016

The AAS Nova site is featured a recent publication in the AAS journal by Paul Bryans of HAO. In the past sungrazing comets have produced extreme ultraviolet emissions as they passed through the sun's corona.

Preparing for the 2017 total Eclipse

On 21 August 2017 a total solar eclipse will pass across the continental United States, from Oregon on the west coast to South Carolina on the east. The eclipse will be a phenomenal experience for the millions of people who see it, but it also offers a unique opportunity to conduct scientific research of the solar atmosphere.
