Prince George THEMIS Ground-based All Sky Imager; Full Resolution Images.
Listed in NASA Data Portal
THEMIS Ground All Sky Imager at Prince George (53.82 deg GLat, 237.17 deg GLong): 256 x 256 pixel full resolution images of auroral oval.
Description
The ASI stations monitor a 170 degree field of view imaging the auroral oval at kilometer resolution. The ASI is comprised of a fisheye lens and CCD in a stainless steel enclosure topped with a transparent acrylic dome.
The CCD has a resolution of 256 x 256 pixels. Exposure control ranges from 5 s to 1 ms although the typical data rate is one image every 3 seconds. Silicone heaters keep the instrument within the nominal temperature range.
