Air-SPEC

(Airborne Infrared Spectrometer)
(a spectrometer used to view the corona during eclipses)

Air-SPEC (for Airborne Infrared Spectrometer) is an instrument developed by the SAO for observing the solar corona during total solar eclipses from an aircraft. It observed during the 2017 and 2019 eclipses.

An improved follow-on, ACES (for Airborne Coronal Emission Surveyor) is an imaging Fourier transform spectrometer rather than a grating spectrometer. ACES was used during the April 2024 eclipse, and plans are to use it in 2026 when an upgrade is completed.
