Real-Time Plot of Auroral Radar Returns at VHF

The University of Alaska, Geophysical Institute, Poker Flat Research Range conducts extensive research involving all aspects of the polar regions. The following plot is generated in real-time and represents conditions as they exist at this instant (graphic plot is updated every minute). The plot is based on aurora radar returns operating at 50 MHz in Anchorage, Alaska and is used here with permission. You can learn much more about the High Latitude Monitoring Station operated by the University of Alaska. Bands of white echo returns in the chart indicate that the radio aurora is returning VHF radio signal echoes in Alaska.
