ASE2023: Eclipse Solar Radius Estimation from a High-Quality Video Recording
JOA 2024, Vol. 14, No. 2, Page 3 Author(s): Luca Quaglia, John Irwin, Jörg Schoppmeyer, Alessandro Pessi,Abstract: A high-resolution, unfiltered, white-light video of the 2023 October 14th annular eclipse (ASE2023), collected very close to the eclipse's northern antumbral path limit, was analysed using the Baily’s beads matching method to obtain an estimate of the eclipse solar radius S ꙩ. By applying the novel idea of the “pivot point” effect and supplementing the analysis by revisiting data collected at the edge of the 2017 February 26th annular eclipse (ASE2017), the following bounds were obtained: 959.90” ≤ Sꙩ ≤ 960.00” at 1 au.
