N.Y. crews part of nationwide effort to record sun’s corona during eclipse

The Sun’s corona, its outermost atmosphere, is typically only visible to the naked eye during a total solar eclipse. The SwRI-led Citizen Continental-America Telescopic Eclipse (CATE) 2024 project evaluated special cameras to measure the polarization of coronal light during the April 2023 total solar eclipse in Exmouth, Western Australia.
