  • 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.

  • Beginning of Summer Time in Chile

    Beginning of summer time in Chile According to Supreme Decree N° 469, dated on June 23, 2011 of the Ministry of Interior, Chile will go into Summer-time on Saturday August 20, 2011.  At midnight on August 20, 2011 all clocks in Continental Chile and Chilean Antarctic must be set forward 60 minutes (1 hour), this is to 01:00 am, Sunday August 21st.   

    Please consider this time change when making plans for observing. The time difference between Chile and UTC (-3hr), Brasília (0hr), US Eastern (+1hr), US Central (+2hr), US Mountain (+3hr), and US Pacific (+4hr).  

  • 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 .  

  • SOAR Adaptive Module (SAM) UV LASER Launch

    SAM UV Laser launch inside the SOAR dome for the first time on January 28, 2011, at 00:30am.  The laser is pointed at a piece of paper attached to the dome, to produce the fluorescent violet light, that is lighting the dome.  This is another important step forward in getting the SAM LGS system online.  

  • SAM Commissioning

      The SOAR Adaptive Module (SAM) is installed at the telescope. During four commissioning nights (Nov 20-23), rich technical data and demo images were collected. So far we use natural guide stars to close the AO loop and to prepare the instrument for operation with the UV laser.
