THEMIS GBO All Sky Imager at Fort Yukon, AK. ASI Thumbnails Data.
Listed in NASA Data Portal
THEMIS Ground All Sky Imager at Fort Yukon (66.56 deg GLat, 214.79 deg GLong): 32 x 32 pixel thumbnails for full ASI images.
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.
