Total Solar Eclipse 2023, Australia

The results of the Shadow-tracking expedition of the Solar Wind Sherpas which was led by Shadia Habbal from the Institute for Astronomy, University of Hawaii at Manoa, are presented on this page. Starting in 2009 the Shadow-tracking/total solar eclipse expeditions have been a joint scientific collaboration between the Institute for Astronomy, University of Hawaii and the Institute of Mathematics, Faculty of Mechanical Engineering, Brno University of Technology.

The 2023 expedition had two observing sites in North West Australia, one in Exmouth at the tip of the Ningaloo peninsula and the other on a small nameless island in the Lowendal Islands further north. The main goal of the expedition was to observe emission from the sequence of Fe X (637.4 nm), Fe XI (789.2 nm), Fe XIII (1074.7 nm), and Fe XIV (530.3nm) lines as well as from the Ar X (553.3 nm) line in the solar corona.
