Title:	The European Solar Telescope: A status update. Part II
Authors:	Hector Socas-Navarro
Abstract:	The European Solar Telescope (EST) is advancing towards its construction phase as the most powerful solar telescope in Europe, designed to observe the Sun at unprecedented spatial and temporal resolution. Featuring a 4.2-meter aperture and an innovative polarization-free optical train, EST integrates a suite of advanced subsystems including an adaptive secondary mirror (ASM), a multi-stage Pier Optical Path (POP), and a Coudé distribution system optimized for high-precision polarimetry and diffraction-limited imaging across a 380–2300 nm spectral range. The project’s baseline includes a design for integrated Multi-Conjugate AO (MCAO), ensuring stable, high-quality correction over a wide field of view. Significant progress has been made in the design but also on the administrative and political fronts to prepare for construction. This presentation is an update of the current status of the project and future steps.
