Detection of "diffuse" coronal He I 1083 during the April 8 2024 Solar Eclipse: evidence for terrestrial atmospheric scattering origin
M. E. Molnar, R. Casini, P. Bryans +2
Strong He I 1083 nm atomic line signals have been previously measured during total solar eclipses at coronal heights above the lunar limb. This rather unexpected measurement has ki…
Coronal Densities, Temperatures and Abundances During the 2019 Total Solar Eclipse: The Role of Multi-Wavelength Observations in Coronal Plasma Characterization
G. Del Zanna, J. Samra, A. Monaghan +7
The Airborne Infrared Spectrometer (AIR-Spec) offers an unprecedented opportunity to explore the Near Infra-Red (NIR) wavelength range. It has been flown at two total solar eclipse…
Optimal spectral lines for measuring chromospheric magnetic fields
P. Judge, P. Bryans, R. Casini +4
This paper identifies spectral lines from X-ray to infrared wavelengths which are optimally suited to measuring vector magnetic fields as high as possible in the solar atmosphere.…
Measuring the magnetic origins of solar flares, CMEs and Space Weather
Philip Judge, Matthias Rempel, Rana Ezzeddine +11
We take a broad look at the problem of identifying the magnetic solar causes of space weather. With the lackluster performance of extrapolations based upon magnetic field measureme…
Observed Variability of the Solar Mg II h Spectral Line
Donald Schmit, Paul Bryans, Bart De Pontieu +3
The Mg II h&k doublet are two of the primary spectral lines observed by the Sun-pointing Interface Region Imaging Spectrograph (IRIS). These lines are tracers of the magnetic and t…
The EUV emission from sun-grazing comets
Paul Bryans, W Dean Pesnell
The Atmospheric Imaging Assembly (AIA) on the Solar Dynamics Observatory (SDO) has observed two sun-grazing comets as they passed through the solar atmosphere. Both passages result…
