Tjautjas/Lycksele realtime riometer data

The graphs are updated every 10th minute.




  • Before 25th April 2019 the measurements at Kiruna were performed using a single-frequency riometers at 30 and 38.2 MHz.
  • From 25th April 2019 the presented frequencies, 30 and 38 MHz, are extracted from the data from Wideband Spectral Riometer. The riometer itself has been situated at Kiruna.
  • Since June 30th 2022, the Wideband Spectral Riometer is located at Tjautjas, near Gällivare.
