Most people have heard about tsunamis in the Earth’s oceans. Those occur when large masses of water get violently moved at the ocean floor, as a result of earthquakes or volcanic eruptions.

Terrestrial and space weather storm scales have a common shortcoming: The scales end at “5.” Nature of course doesn’t know this and sometimes produces a disturbance that is simply off the charts.

Graph depicting Coronal Wind Mass-Loss Rate
March 7, 2019

We derive an explicit expression for the coronal wind mass-loss rate. This result is based on a currently used generalized torque formula (per unit rotational velocity) expressed as a product of known monomials, separately for the magnetic field and the mass-loss rate.

Multiple scatter plots of Geomagnetic storms

To address challenges of assessing capabilities of space weather modeling, the CCMC (Community Coordinated Modeling Center) is leading a newly established “International Forum for Space Weather Modeling Capabilities Assessment.”

Graph depicting the transformation of the PCA basis through a series of carefully chosen rotations

We investigate the application of 2-dimensional Principal Component Analysis (2D PCA) to the problem of removal of polarization fringes from spectro-polarimetric data sets.

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.
