Investigating Pre-flare Signatures in Spectroscopic Observations of an X9-class Solar Flare

Louis Seyfritz, Maria Kazachenko, Ryan French

On October 3rd, 2024, the Sun emitted an X9.0-class flare from active region NOAA 13842. The event was recorded by multiple space-based instruments, beginning hours before the erup…

Spectral Irradiance Variability in Lyman-Alpha Emission During Solar Flares

Luke Majury, Ryan Milligan, Elizabeth Butler +2

The Lyman-alpha (Lyα;1216 à ) line is the brightest emission line in the quiescent solar spectrum and radiates a significant fraction of the available nonthermal energy during fla…

Investigating the Magnetic Imprints of Major Solar Eruptions with SDO/HMI High-Cadence Vector Magnetograms

Xudong Sun, J. Todd Hoeksema, Yang Liu +2

The solar active region photospheric magnetic field evolves rapidly during major eruptive events, suggesting appreciable feedback from the corona. Previous studies of these "magnet…

Quantifying Poynting flux in the Quiet Sun Photosphere

Dennis Tilipman, Maria Kazachenko, Benoit Tremblay +3

Poynting flux is the flux of magnetic energy, which is responsible for chromospheric and coronal heating in the solar atmosphere. It is defined as a cross product of electric and m…
