Paper Abstract

The Atacama Large Millimeter/submillimeter Array (ALMA) is a major new interferometer operated on Llano de Chajnantor at 5050 m altitude in the Chilean high Andes. This location is considered one of the world's outstanding sites for submillimeter astronomy. ALMA is still under construction, but science observations has started already in what is commonly known as ALMA Early Science Cycle 0. The purpose of ALMA Early Science Cycle 0 is to deliver scientically useful results to the astronomy community and to facilitate the ongoing characterization of ALMA systems and instrumentation as the capability of the array continues to grow. Early Science will continue through Cycle 1 and until construction and commissioning of ALMA is complete. This publication aims to give an insight into the challenges we face operating telescope of this scale at Chajnantor, a plateau 4800{5100 meter above sea level in one of the driest places of earth. It also will also present statistics from the proposal submission, describe the path from an accepted proposal to a calibrated data product, and nally an outlook for the future.
