HiWind
April 3, 2018

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
March 26, 2018

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.

responses at 120 km due to different lower boundary forcing of the TIEGCM
May 11, 2018

New mechanisms for imposing planetary-wave (PW) variability on the ionosphere thermosphere system are discovered in numerical experiments conducted with the National Center for Atmospheric Research (NCAR) Thermosphere-Ionosphere- Electrodynamics General circulation Model (TIE-GCM).

A short guide to spectroscopy is given, with emphasis upon the elementary physics needed to understand and begin modeling the radiation emerging from astrophysical plasmas using the Sun as a guide, without bias towards a particular region of the Sun's atmosphere.

UT and altitude variations of electron densities
May 4, 2018

The high-resolution thermosphere-ionosphere-electrodynamics general circulation model (TIEGCM) was used to investigate the cause of F2-region electron density (Ne) responses to the Great American Solar Eclipse on 21 August 2017 at Millstone Hill (42.610N, 71.480W).

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).

GET K-COR DATA

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.
