Baily's Beads Observation during the Hybrid Solar Eclipse 2023 April 20
JOA 2023, Vol. 13, No. 4, Page 12 Author(s): Konrad GuhlAbstract: The timing of Baily’s Beads, observed during a solar eclipse is one of the most accurate ground-based methods for estimating the solar radius. In 2023, IOTA/ES organised an expedition to the northern edge of the total part of the hybrid solar eclipse (TSE) on April 20, where bead observation was possible. The timing was measured by photometry in FITS files. The correction to the solar radius of Δ Rs = 0.38” was derived from this observation.
