• 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).

  • First Snow of 2015 at Cerro Tololo and Cerro Pachon

    During the weekend of July 12-13 the first snow storm of the season hit the Chilean Andes in the region of the Cerro Pachón and Cerro Tololo observatories. Roughly 70cm of snow acumulated on the Pachón summit and the main access road was partly washed out not far from the main gate.

  • 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.

  • SOAR Adaptive Module (SAM) Closes the Loop

      SAM closes the loop The loop was closed on the laser guide star on April 15. Next night, the improvement of the image quality in closed-loop was documented by images of bright stars. Side-by-side comparison of PSFs in the green and red are shown in the image, with FWHM indicated .
