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 à ) line is the brightest emission line in the quiescent solar spectrum and radiates a significant fraction of the available nonthermal energy during fla…
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; 1216à ) emission from solar flares, regular observations of flare related Lyα have been relatively scarce until recently.…
