The first generation of ELT instruments includes an optical-infrared high resolution spectrograph, indicated as ELT-HIRES and recently christened ANDES (ArmazoNes high Dispersion Echelle Spectrograph). ANDES consists of three fibre-fed spectrographs ([U]BV, RIZ, YJH) providing a spectral resolution of ∼100,000 with a minimum simultaneous wavelength

The European Solar Telescope (EST) is a 4-m class-solar telescope that will become part of the next generation of groundbased facilities. Located at the "Observatorio del Roque de los Muchachos" in La Palma (Spain), it will be aimed to study the magnetic connectivity of the solar atmosphere with high spatial and temporal resolution. The EST optical

Approximately 15% of the near-Earth asteroid (NEA) population are estimated to be binary systems. 54 binaries have Arecibo radar observations; 2020 BX 12 is one of them. Discovered on January 27, 2020, by the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey at Mauna Loa Observatory, 2020 BX 12 has an absolute magnitude of 20.6 and an
