Construction site at an altitude of 5000 m above sea level was hit by very strong wind. As the wind broke a horn of one of the antennas for radio seeing monitor at the base, staff members had to work very hard to repair it. The picture shows an antenna whose direction to face was changed by the wind (left) and another antenna for radio seeing monitor (right). The small object on the left is ASTE 10-m submillimeter telescope of NAOJ while the another small objects in the center are observatory containers for NANTEN telescope of Nagoya University.
