Imaging Riometer Observations of ionospheric absorptions of cosmic radio noise using the imaging riometer at Ny-Alesund in Svalbard have continued since September 1991, with support from the Norwegian Polar Research Institute and in collaboration with the University of Oslo. The observations are coordinated with two riometers in Greenland and the riometer at Tjorness in Iceland in collaboration with the Danish Meteorological Institute and National Institute of Polar Research in Japan, respectively.
