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…

Quasi-Periodic Pulsations in Ionospheric TEC Synchronized with Solar Flare EUV Emission
Aisling N. O'Hare, Susanna Bekker, Laura A. Hayes +1
The extreme ultraviolet (EUV) and X-ray radiation emitted during solar flares has been shown to significantly increase the electron density of the Earth's ionosphere. During flares…
