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.

MHD models to predict the magnetic structure of the corona at the time of the eclipse
June 28, 2019

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.

October 8, 2019

One of the most robust features of the solar magnetic cycle is that the stronger cycles rise faster than the weaker ones. This is popularly known as the Waldmeier Effect, which is known for more than 100 years.

The magnetic field in the corona is important for understanding solar activity. Linear polarization measurements inforbidden lines in the visible/IR provide information about coronal magnetic direction and topology.

Schematic of plasma and density structures in the IT system
October 3, 2019

In this paper we discuss, in a limited way, some of the challenges to advancing our understanding and description of the coupled plasma and neutral gas that make up the ionosphere and thermosphere (I-T).

CoMP Coronal Intensity

The COronal Multi-channel Polarimeter (CoMP) observes the Fe-XIII emission line at 1074.7 nm to measure the coronal magnetic field and obtain plasma density and motion in the low corona from ~1.03 to 1.5 solar radii.


K-Cor White Light Corona

Designed to study the formation and dynamics of coronal mass ejections and the evolution of the density structure of the low corona, K-Cor records the polarization brightness (pB).


K-Cor (radially graded filter)

K-Cor image with a normalized radially graded filter (nrgf) to maximize image contrast, especially in the outer field.

These data are ideal for measuring positions of coronal structures such as CMEs and helmet streamers.
