Auroral Large Imaging System (ALIS) (ALIS)

Updated 2012-07-19

In and around Kiruna, IRF uses all-sky cameras and other images to detect and record the aurora. The all-sky cameras have 180° field-of-view and take one image per minute. They have been in operation since the International Geophysical Year (IGY) in 1957 (Table 6, #9.1). The Auroral Large Imaging System (ALIS) is a large-scale array of high-resolution monochrome CCD detectors around Kiruna, a network of seven stations within approximately 50 x 50 km. The International Network for Auroral Optical Studies of the Polar Ionosphere, coordinated by IRF, is a forum for planning measuring campaigns, distributing information, and intercalibrating different sets of instruments located in different parts of the world. The network is part of the IPY-endorsed project Heliosphere Impact on Geospace (IPY Cluster #63), with Interhemispheric Conjugacy Effects in Solar-Terrestrial and Aeronomy Research (ICESTAR) and International Heliophysical Year (IHY) as lead projects.
