A common tool in auroral science is the all-sky camera. This is simply a camera fitted with a fish-eye lens and pointed upwards. This way it is possible to image the sky from horizon to horizon in all directions. Science grade all-sky cameras are sophisticated instruments with very high light sensitivity and ability to look at single light emissions at high time resolution.<\/p>\n

In Troms\u00f8 all-sky cameras have been in operation since the international geophysical year in 1957\/58. The particular camera originally used was designed by Willy Stoffregen, one of the pioneers in optical instrumentation for auroral research. Here are two pictures showing the all-sky camera design and the particular one in Troms\u00f8:<\/p>\n

Below we show an all-sky camera image taken with the not-science grade camera at the Auroral Observatory in Troms\u00f8. This camera has a sensitivity comparable to the human eye, which makes it useful to check if there is aurora outside without leaving the sofa:<\/p>\n

All-sky cameras are also popular among amateur astronomers to check the cloud cover and also among meteorite hunters. In Norway the Norwegian Meteor Network<\/a> is setting up all-sky cameras in order to identify meteors\/fireballs.<\/p>\n

In the auroral zone Auroral tourism is a rapid growing industry. Among auroral guides it is very common to use real-time all-sky camera data in order to monitor the aurora and cloud conditions.\u00a0The Norwegian Center for Space Weather is looking into setting up more all-sky cameras in Northern Norway in support of the auroral tourism industry. Here we have compiled a list of links to the pages in Northern Fennoscandia where all-sky images may be viewed in real-time, note that science grade cameras are usually turned off when the moon is up:<\/p>\n
