Yesterday night(2019-04-15), azimuth slave motor stopped several times at high speed motion. For the reserved schedules, maximum speed is temporary reduced to 1 deg/s and it works well. But the motor seems to be damaged, and it should be replaced. The replacement work is scheduled on the next maintenance day(Monday, 22nd April). But, if the motor become worse and observation is impossible, the motor will be substituted immediately. If you have any questions on the observing time, please contact our staff.
