While solar radiation enables and sustains life on Earth, it also produces “space weather” that can profoundly impact different technologies, including telecommunications, satellite navigation, and the electric power grid. Solar flares can produce x-rays resulting in radio blackouts that block high-frequency radio waves.

Previous studies have established the importance of the increasing greenhouse gas concentrations in causing trends in the thermosphere and ionosphere (T-I). Recent work indicates that the changing Earth’s magnetic field is also important.

Solar flare effects on magnetospheric convection and ionospheric potential.
June 18, 2021

Solar flares—a sudden eruption of electromagnetic radiation at the Sun—are known to have significant impacts on Earth’s upper atmosphere and ionosphere, but their collective effects on geospace as an integrated system have never been examined.

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.
