NASA's recently-funded Small-Explorer (SMEX) mission, PUNCH (Polarimeter to UNify the Corona and Heliosphere), is targeted to launch in 2022. Sarah Gibson, interim director of the High Altitude Observatory at the National Center for Atmospheric Research (NCAR), is coordinating the mission’s innovative science efforts.

Seeker, an American digital media network and content publisher, interviewed HAO's space scientist, Delores Knipp, in July 2019. The presentation is titled "How Earth's Magnetic Field Twists and Buckles During Solar Storms." Dr. Knipp uncovered a war mystery that is connected to a major solor storm event in July 1972.

A puzzling feature of the Earth’s equatorial upper atmosphere is the occurrence of enhanced VHF radar echoes near 150-km altitude. These so-called 150-km echoes have been observed for over 50-years, and occur nearly every day, making them a persistent feature of the equatorial ionosphere.

One of the most robust features of the solar magnetic cycle is that the stronger cycles rise faster than the weaker ones. This is popularly known as the Waldmeier Effect, which is known for more than 100 years.

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.
