An Airborne Coronal Emission Surveyor (ACES) for Solar Eclipse Observations

The Airborne Coronal Emission Surveyor (ACES) is a new imaging Fourier transform spectrometer (FTS) that will explore the large-scale coronal infrared (IR) emission spectrum during the April 8, 2024 total solar eclipse. ACES will fly along the path of totality on the NSF/NCAR Gulfstream V High-performance Instrumented Airborne Platform for Environmental Research (GV HIAPER) with a stabilized solar feed provided by the Airborne Stabilized Platform for InfraRed Experiments (ASPIRE). During the six-minute total eclipse, ACES will map emission line intensity in the 1–4 µm wavelength region over a 0.73 ◦ × 0.55 ◦ field of view (FOV).
