  • SOAR held its Review Commitee 2015

    SOAR External Review Committee at the telescope

    Every five years during the course of observatory operations, SOAR holds an external review – roughly the equivalent of a visiting committee at universities. SOAR held its second such review this past June 24-26, in La Serena and on Cerro Pachón. In addition to hearing presentations from the Director, Board and SAC, the committee visited the telescope (see the accompanying photo).

  • The SOAR Adaptive Optics Module (SAM) takes a sharp look at HH-46/47

    During the night of February 14, 2015, Drs. Cesar Briceño and Steve Heathcote (CTIO) used the SOAR Ground Layer Adaptive Optics Module (SAM) to obtain these ~0.45” FWHM images (under seeing of 0.9”) of the Herbig-Haro objects HH 46 and 47, located in the Vela star forming region. Obtained as a pilot observation for their NOAO program 2015A-0296, these are probably the sharpest ground based optical images ever obtained of these objects.
