ESO Internal Workshop

ESO Internal Workshop on
Forecasting Astronomical Observing Conditions

European Southern Observatory, Garching bei München, Germany

29-30 May, 1997

ESO Council Room

Executive Summary

available also as a compressed postcript file

PURPOSE

It is now understood that most future ground based observatories will make use of flexible scheduling tools to select the observing mode best adapted to the observing conditions.

ESO has been conducting a wide survey of existing and potential forecasting techniques and several feasibility studies are close to completion. It is thus time to prepare the specifications of the operational tools and services to be developped for the VLT.
