Abstract

During the December 2020 total eclipse we registered time resolved light measurements of incident solar light with VIS-NIR photodiodes in northern Patagonia. Signals compatible with the observation of shadow bands in the 200 s before and after totality were observed. A strong increase in the normalized noise spectral densities of recorded incident radiation near totality suggests the presence of shadow bands. Originally high-altitude balloon measurements and spatial correlation ground measurements were planned, but the harsh climate conditions limited the campaign’s results.
