• Welcome to the New SOAR website

    We hope you will find here a useful guide to the SOAR Telescope. These pages aim at being the source of practical information for the professional astronomer who wants to submit observing proposals for SOAR, or who, as a SOAR user, needs to plan an observing run, or requires technical information/tools to aid in the data reduction process.  If you notice issues or have suggestions to help us improve our web pages, please contact us

    The Southern Astrophysical Research (SOAR) Telescope is a 4.1 meter aperture telescope designed to produce the best quality images of any observatory in its class in the world, across a several arcmin field of view. Capable of working from the atmospheric cut-off in the blue (320 nm) to the near infrared, it features fast slewing and a suite of both optical and infrared instruments mounted and ready for use. It was funded by a a partnership between the U.S. National Optical Astronomy Observatory (NOAO), the Ministério da Ciencia e Tecnologia of the Federal Republic of Brazil (MCT), the University of North Carolina at Chapel Hill (UNC), and Michigan State University (MSU). SOAR is situated on Cerro Pachón - IV Region - Chile, at an altitude of 2,700 meters (8,775 feet) above sea level.

    In addition to excellent image quality within its up to 10 arcmin field, SOAR offers:
    1. A modern high throughput optical spectrograph with high UV/blue sensitivity
    2. Several other optical and near-IR instruments, which are always mounted and can be switched in a matter of minutes
    3. Routine remote observation via VNC and video links, which allows projects sharing time during a night, and enables scientists to personally and efficiently carry out synoptic programs requiring full or partial nights distributed over weeks or months.
