The Atmospheric Imaging Assembly (AIA) on the Solar Dynamics Observatory (SDO) provides high-resolution, full-disk images of the Sun's corona and transition region up to 0.5 solar radii above the limb, with a spatial resolution of 1.5 arcseconds and a temporal resolution of 12 seconds. AIA consists of four telescopes equipped with normal-incidence, multilayer-coated optics, enabling narrow-band imaging of seven extreme ultraviolet (EUV) band passes centered on specific lines. These band passes cover a wide range of temperatures from 6 × 10^4 K to 2 × 10^7 K. The AIA was launched as part of NASA's SDO mission on February 11, 2010, and aims to advance our understanding of solar variability and the mechanisms by which the Sun's energy is stored and released into the heliosphere and geospace. The instrument's capabilities include high signal-to-noise ratios, continuous viewing for months at a time, and the ability to study energetic transient phenomena. AIA's observations are crucial for understanding the dynamic magnetic field, coronal heating, transients, connections to geospace, and coronal seismology, contributing to the broader goals of the SDO mission.The Atmospheric Imaging Assembly (AIA) on the Solar Dynamics Observatory (SDO) provides high-resolution, full-disk images of the Sun's corona and transition region up to 0.5 solar radii above the limb, with a spatial resolution of 1.5 arcseconds and a temporal resolution of 12 seconds.
