| contents | Eclipse shadow bands are transient intensity patterns that can appear on the ground near solar eclipse totality. This study presents a reusable image-processing framework for analyzing shadow-band video recordings collected with consumer-grade cameras. The framework quantifies band orientation, band prominence, and band power spectral density from video recordings. Applied to two eclipse datasets, the method detected statistically significant shadow-band activity during eclipse windows that align with the scintillation theory for shadow bands. The results also highlight simultaneous superimposed eclipse shadow band modes with orthogonal orientations. This demonstrates that consumer grade cameras can support quantitative analysis of shadow bands and may support future observational and atmospheric studies. |
