View current North Polar aurora conditions - in real-time - courtesy of auroral radar at the University of Alaska. Also view the boundaries of the aurora - measured in real-time by satellites, or follow the link at the page bottom to European aurora conditions.
If you chase DX, you know that interesting propagation conditions often form along the so called "gray line" marking the boundary between day and night. You can view the current day/night boundaries, in real-time.
From the Australian Space Forecast Centre. Covers both Australia and the southern hemisphere and now includes real-time data for North America. Excellent data resource and graphical representation of current conditions.
