Scientists from the University of Padua will test a new solar instrument during a total solar eclipse on Aug. 12, 2026 [1].
The mission aims to advance solar corona research by capturing data more efficiently than current technology allows. Because total eclipses provide a rare window to observe the Sun's outer atmosphere without interference from the bright solar disk, the timing is critical for the team.
The researchers are deploying the Circular Slit Spectrometer, known as CISS [1]. This device is designed to analyze the solar corona by breaking down the Sun's light into its constituent wavelengths [2]. The team said the CISS can perform these analyses faster than existing spectrometers [1].
The test will take place at the Javalambre Astrophysical Observatory in Spain [1]. This location was selected to provide the necessary conditions for the observation during the peak of the eclipse [1].
By increasing the speed of data collection, the CISS could provide a more detailed understanding of the solar corona's dynamics [2]. The University of Padua team said the instrument will allow for more precise measurements of the solar atmosphere's composition, and behavior during the brief window of totality [3].
Existing spectrometers often require longer exposure times, which can limit the amount of data gathered during the short duration of a total eclipse. The CISS aims to solve this limitation by streamlining the light-analysis process [2].
“The mission aims to advance solar corona research by capturing data more efficiently than current technology allows.”
The successful deployment of the Circular Slit Spectrometer would represent a technical leap in heliophysics. By reducing the time required to capture spectral data, scientists can observe more rapid changes in the solar corona, potentially leading to better predictions of solar flares and space weather that affect satellite communications on Earth.
