Sunrise Balloon Launching
April 7, 2017

The March issue of NOVA features Sunrise, the scientific collaboration that twice launched the largest balloon-borne solar telescope to ever leave the Earth's surface. Launched from the Esrange Space Center in Kiruna, Sweden, it was carried aboard the HAO-developed gondola.

Delta II rocket launching the fifth GPS IIR(M) satellite
April 4, 2017

As part of the US National Space Weather Strategy and Action Plan, and following the 2016 Executive Order 13744, the Department of Defense (DoD) is now opening a more than 15-year record of GPS particle data to scientific scrutiny.

Stokes profiles of the Fe I transition
May 9, 2017

We investigate atomic transitions that have previously been identified as having zero polarization from the Zeeman effect. Our goal is to identify spectral lines that can be used for the calibration of instrumental polarization of large astronomical and solar telescopes, such as the Daniel K.

Coronal pseudostreamer magnetic topology
May 1, 2017

Magnetic fields in the sun's outer atmosphere, the corona, control both solar-wind acceleration and the dynamics of solar eruptions.

 Synthetic ultraviolet global images
April 27, 2017

The Global Airglow (GLOW) model has been updated and extended to calculate ultraviolet light emitted by the upper atmosphere, including during the day, the night, and in the aurora.

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.
