In February, 2018, a specialized engineering team, led by principal investigator Dr. Qian Wu, traveled from Boulder, Colorado to a NASA facility in Palestine, Texas. The team spent two weeks working with NASA colleagues performing compatibility testing between the HiWIND electrical systems and the NASA balloon command and control communications systems.

50-year time series of the S-index

During his thesis work at HAO, Newkirk Fellow Ricky Egeland developed a solar-stellar database called sunstardb. The "solar-stellar connection" began as a relatively small field of research focused on understanding the processes that generate magnetic field in stars and sometimes lead to a cyclic pattern of long-term variability in activity, similar to the one demonstrated by our Sun.

The lower atmospheric forcing effects on the ionosphere are particularly evident during extreme meteorological events known as sudden stratospheric warmings (SSWs).

Whole Atmosphere Community Climate Model (WACCM) simulations are used to investigate the short-term (30-day) temporal variability in the mid- and high-latitude Southern Hemisphere mesosphere.

Comparison of measured to modeled global total electron content

Solomon & Qian show that solar minima are not all the same, and may have implications for understanding the Sun during the extended periods of very low activity known as “grand minima” that have sometimes occurred in the past, the best known of which was the Maunder Minimum during 1650–1700.

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.
