The seeing at Dome A, Antarctica is expected to be similar to the superb seeing at Dome C, a median of about 0:003. However, there has not been direct night seeing measurement yet, because unattended DIMM (Differential Image Motion Monitor) is hard to be operated automatically over the winter at Dome A. To solve this problem, we propose an automatic DIMM for Kunlun Station at Dome A, named KLDIMM. Here we will present the hardware design, software system and results of cold laboratory test. This system will be tested at sites in China and calibrated to other DIMMs, then installed on an 8-m tall customized tower at Dome A in January 2019.
Kunlun Cloud and Aurora Monitor (KLCAM) is an all-sky camera with intensive thermal control designs specifically for the harsh environment at Dome A, Antarctica. The prototype of KLCAM was installed at Kunlun Station, Dome A in early 2017 and has worked under unattended condition non-stop through the polar nights successfully. KLCAM collects data for site testing as well as providing real-time observing conditions for the operation of the Antarctic Survey Telescope (AST3).
