Description
Magnetic field is the most important observational quantity in contemporary solar physics, as nearly all solar activities are closely associated with the solar magnetic field and its evolution. Currently, measurements of the solar magnetic field are primarily based on the Zeeman effect, where longer wavelengths offer higher detection precision and sensitivity. Therefore, conducting solar magnetic field observations in the mid-infrared band is the most effective approach to improving the accuracy of solar magnetic field measurements. The 1-m off-axis mid -infrared solar magnetic field telescope (AIMS) is the first solar telescope dedicated to mid-infrared solar magnetic field measurement in the world. The first-generation scientific instruments of AIMS are a 12.32 μm Fourier Transform Spectrometer and an 8–10 μm imager. After a decade of development, AIMS began scientific observations in October 2025. This report highlights the latest development progress and observational results of AIMS: AIMS has observed triply-split spectral lines in solar active regions and spectral evolution during solar flares at the 12.32 μm, and has captured multiple instances of radiation enhancement associated with solar flares using its 8–10 μm imager.
