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.

BC Low elaborates on the extraordinary sixty years of progress made to space observation of the Sun, solar wind, planets and their magnetospheres. He notes that space platforms complementing ground-based observatories have transformed solar physics.

The time evolution of height-dependent (a) electron density, (b) ionization rate, (c) Pedersen conductivity, and (d) Hall conductivity at MLT = 6 and magnetic latitude of 60

Stan Solomon et al, dicuss a new modeling capability that self-consistently couples physics-based magnetospheric 18 electron precipitation with its impact on the ionosphere, representing a significant improvement over previous models.

Change in WACCMX simulated total electron content (TEC) during a geomagnetic

Nicholas Pedatella notes that geomagnetic storms are an important driver of variability in Earth’s ionosphere, and can have significant societal impacts through the ionosphere’s impact on communications and navigation systems (e.g., GPS).

MLSO Latest Images

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.
