Resumen:
<!-- @page { size: 8.5in 11in; margin: 0.79in } P { margin-bottom: 0.08in } --> We present an overview on the new instrumentation for the H-alpha Solar Telescope of Argentina (HASTA), located in “El Leoncito” at the Observatorio Astronómico “Félix Aguilar” in Argentina, which extends its capabilities to observe the solar Chromosphere. Full frame observations of the complete solar disk are made at the H-alpha center line and also at the line wings, with increased spatial and temporal resolution. A new 14 bits, 1600x1200 pixels CCD camera, the development of new image acquisition routines of 2 frames per second, a new Flat Fielding procedure, a new automatic focusing device, new flare classification routines and a web portal access of online images and daily movies, allows for a more detailed study of the solar activity, chromospheric wave propagation and fast impulsive events. A permanent observer’s staff also allows for a continuous solar watching.
