The EUV Late-Phase: Statistical Results from 15 Years of Solar Dynamics Observatory Observations

Harry J. Greatorex, Aisling N. O'Hare, Susanna Bekker +3

Since its launch in 2010, the Solar Dynamics Observatory (SDO) has provided continuous, high-cadence, multi-wavelength observations of the Sun, capturing thousands of solar flares…

Investigating a Characteristic Time Lag in the Ionospheric F-region's Response to Solar Flares

Aisling N. O'Hare, Susanna Bekker, Harry J. Greatorex +1

X-ray and EUV solar flare emission cause increases in the Earth's dayside ionospheric electron density. While the response of the lower ionosphere to X-rays is well studied, the de…

Spectral Irradiance Variability in Lyman-Alpha Emission During Solar Flares

Luke Majury, Ryan Milligan, Elizabeth Butler +2

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

On the Instrumental Discrepancies in Lyman-alpha Observations of Solar Flares

Harry J. Greatorex, Ryan O. Milligan, Ingolf E. Dammasch

Despite the energetic significance of Lyman-alpha (Lyα; 1216Å) emission from solar flares, regular observations of flare related Lyα have been relatively scarce until recently. Adv…

Observational Analysis of Lyman-alpha Emission in Equivalent Magnitude Solar Flares

Harry J. Greatorex, Ryan O. Milligan, Phillip C. Chamberlin

The chromospheric Lyman-alpha line of neutral hydrogen (Ly; 1216 Å) is the most intense emission line in the solar spectrum, yet until recently observations of flare-related Ly$…
