In Fond Memory

We are deeply saddened to acknowledge the loss of
Michael J Thompson. He was a scientist, Director, mentor, colleague, collaborator, and friend. A very thoughtful and kind human being. All in HAO, and many of our colleagues around the world, are shocked at Michael’s sudden passing. Our most sincere sympathy and thoughts are with Michael’s wife Kate, son Robin, and their friends at this time.

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.
