IGRINS was removed today from telescope to leave way for GHOST installation. After that, IGRINS will go through a scheduled maintenance by a team from KASI, and it will back at the telescope on October 17th.
Following successful checks on Friday after the yearly engineering shutdown, IGRINS is back doing observations. The instrument will remain on the telescope until Sept 7th.
After the heavy snowtorms that affected Pachon, telescope operations have resumed, and IGRINS will be available for a short time starting tonight until the beginning of the yearly engineering shutdown.
General maintenance has been scheduled for IGRINS between September 5th and 16th, when the instrument will be unavailable. A visiting team from KASI at Pachon will execute several tasks, including the replacement of one of the cold heads.
After the completion of the GHOST commissioning, the GHOST Cassegrain Unit was removed from the telescope and IGRINS was installed back on the same port last Monday. Back on sky checks were performed successfully on Tuesday night and the instrument was used immediately for science operations.
