Abstract

SCHMIEGELOW, Christian T. et al. Observation of atmospheric scintillation during the 2020 total eclipse in northern Patagonia. Pap. Phys. [online]. 2022, vol.14, pp.142-149.  Epub Jan 20, 2022. ISSN 1852-4249.  http://dx.doi.org/10.4279/pip.140013.

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.
