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.

On October 6th, the MLSO staff participated in AstroDay 2018, an educational outreach event coordinated by the Mauna Kea Observatories. 3,000 people attended. This was the second occurrence of this event, located in Kailua-Kona, on the west side of Hawaii Island.

H & K emission cycles for the Sun
September 18, 2018

Life imitates art, sometimes remarkably well... A recent paper has announced the discovery of an exoplanet around the nearby star 40 Eridani, which had previously been identified as the host star of Vulcan, the fictional home world of Star Trek’s cultural icon, Mr. Spock.

Solar irradiance models indicate that irradiance variations are dominated by changes in disk-coverage of magnetic structures, whose brightness is thought to be determined by their size and average magnetic flux density.

The nighttime mesopause, marking the boundary of mesosphere and thermosphere and having the coldest atmospheric temperature, is formed mainly by the combination of radiative cooling by CO2, and the adiabatic flow in the Mesosphere and Lower Thermosphere.

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.
