摘要：

We present here a new solar telescope in H alpha. HASTA ("H-Alpha Solar Telescope for Argentina") has been set up at the OAFA mountain astronomical observatory "Carlos U. Cesco" in El Leoncito, San Juan, Argentina, because of the unique clearness of the sky almost all year around. HASTA has a spatial resolution of 1.5 arcsec and temporal resolution of up to 3 sec. It started operations in May 1998. HASTA complements three other solar instruments which have been or are being installed in El Leoncito: MICA, a mirror coronagraph that observes the solar corona above the limb from 1.05 to 2 solar radii, a sub-millimeter solar telescope (SST) for measurements up to Far Infrared, and a high resolution imaging spectrograph (BLISP).
