At the end of October last year，Hu Zhongwen(Associate fellower of NIAOT)left for Antarctica to participate scientific expedition。

After two months of arduous trek with the 26th Chinese Antarctic expedition team，he successfully reach highest point of the Antarctic inland Dome A。

During in Dome A for 21 days and nights, Hu Zhongwen and Shang Zhaohui(Professor of Tianjin Normal University) successfully completed scheduled tasks:

1)：to maintain and update astronomical instruments in Dome A，including CSTAR and international cooperation project PLATO as well as SNODAR(measurement of atmospheric turbulence near the ground and the boundary layer)；

2)：installation FTS(THz Fourier transform spectrometer) and SHABAR (moonlight scintillometer for measuring atmospheric turbulence 100 meters above the ground;

3)：site-selection and foundation preparation for the Antarctic Schmidt telescope AST3 (3 sets of large field of view telescope with aperture of 68cm for main mirror，50cm for pupil plane)

Hu Zhongwen also installed Chinese first Antarctic aurora spectrograph commissioned by Chinese Polar Research Center at Zhongshan Station。

This aurora spectrograph can be realized up to 30 different exposure time parameter setting，the software can automatically adjust the exposure parameters based on brightness。

It can understand the upper atmosphere by observing the aurora magnetic field，analyse the physical characteristics of the aurora and chemical composition, reveal much more solar wind activity rules。

Aurora spectrograph has been plunged into play, and obtained the first auroral spectrum。

Hu Zhongwen has also brought back the CSTAR observation data during last winter。

The Antarctic expedition further promote the process of building Chinese Antarctic Observatory。

AST3 has been basically completed by NIAOT，which will be sent to DOME A with the 27th Antarctic expedition team。It will become the first inland Antarctic automatic tracking and remote control telescope。

2 m to 4 m class optical infrared telescope will be developed by NIAOT for construction of the Antarctic Observatory。
