Auroral images at frequencies 6300 A, 5577 A, 4278 A, and white light taken at the Argentinian antarctic station Belgrano II
Listed in NASA Earthdata CMR
Optical observations of auroral displays are performed by a camera with a field of view of 180 degrees: the all-sky camera.
Description
A prototype camera has been delivered to the Argentinian base General Belgrano II.The present instrument has been equipped with a 512x382 CCD and a filter wheel housing three filters in order to provide spectral discrimination at 630.0 nm, 557.7 nm and 427.8 nm. The instrument is capable of acquiring an image in about one minute and an half.
The camera is operational during the entire antarctic winter and images are taken when the solar terminator is above 300 km. The data will be transmitted to Italy at the end of the observational campaign and collected in the data center. Source name: Ground Station > Argentinian Base General Belgrano II, Antarctica
