Monochromatic all-sky CCD image data

This is a Sino-Japan collaborative observation at Zhongshan, Antarctica, which commenced March 1998 (Principal Investigators: Prof. Natsuo Sato, National Institute of Polar Research and Dr. Huigen Yang, Polar Research Institute of China). The observation system comprises a CCD camera fitted with a fish-eye lens and an interference filter, which can be manually changed between the two target auroral lines on 557.7nm and 630.0nm. The HAMAMATSU Photonics's C4880-37 CCD camera provides images with a spatial resolution of 512*512*12 bits. The exposure time is set to 15 seconds in observation and image data are originally recorded on DVD RAM disks.
