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.

2020年巴塔哥尼亚北部日全食期间的大气闪烁观测

在2020年12月的日全食期间，我们在巴塔哥尼亚北部用VIS-NIR光电二极管记录了入射太阳光的时间分辨光测量结果。在全食前后的200秒内观察到与阴影带观测结果相一致的信号。在全食附近记录的入射辐射的归一化噪声谱密度的强烈增加表明存在阴影带。最初计划进行高空气球测量和空间相关性地面测量，但恶劣的气候条件限制了活动的结果。

期刊介绍： Papers in Physics publishes original research in all areas of physics and its interface with other subjects. The scope includes, but is not limited to, physics of particles and fields, condensed matter, relativity and gravitation, nuclear physics, physics of fluids, biophysics, econophysics, chemical physics, statistical mechanics, soft condensed matter, materials science, mathematical physics and general physics. Contributions in the areas of foundations of physics, history of physics and physics education are not considered for publication. Articles published in Papers in Physics contain substantial new results and ideas that advance the state of physics in a non-trivial way. Articles are strictly reviewed by specialists prior to publication. Papers in Physics highlights outstanding articles published in the journal through the Editors'' choice section. Papers in Physics offers two distinct editorial treatments to articles from which authors can choose. In Traditional Review, manuscripts are submitted to anonymous reviewers seeking constructive criticism and editors make a decision on whether publication is appropriate. In Open Review, manuscripts are sent to reviewers. If the paper is considered original and technically sound, the article, the reviewer''s comments and the author''s reply are published alongside the names of all involved. This way, Papers in Physics promotes the open discussion of controversies among specialists that are of help to the reader and to the transparency of the editorial process. Moreover, our reviewers receive their due recognition by publishing a recorded citable report. Papers in Physics publishes Commentaries from the reviewer(s) if major disagreements remain after exchange with the authors or if a different insight proposed is considered valuable for the readers.
