When to see the Southern Lights with these online predictors to get the best views.

The following NOAA forecasts are based on the forecast of the planetary geomagnetic activity index: Kp. The higher the Kp index (>5), the more chance you have of seeing the southern Auroras...

OVATION Aurora Forecast Model: 30 minute prediction

The OVATION Aurora Forecast Model shows the intensity and location of the aurora predicted for the time shown at the top of the map. This probability forecast is based on current solar wind conditions measured at L1, but using a fixed 30-minute delay time between L1 and Earth. A 30-minute delay corresponds to approximately 800 km/s solar wind speed as might be encountered during geomagnetic storming conditions. In reality, delay times vary from less than 30 minutes to an hour or so for average solar wind conditions.

The sunlit side of Earth is indicated by the lighter blue of the ocean and the lighter color of the continents. The day-night line, or terminator, is shown as a region that goes from light to dark. The lighter edge is where the sun is just at the horizon. The darker edge is where the sun is 12 degrees below the horizon. Note that the aurora will not be visible during daylight hours; however, the aurora can often be observed within an hour before sunrise or after sunset. The red line at about 1000 km equatorward of the brightest aurora indicates how far away viewers on the ground might see the aurora assuming good viewing conditions.

OVATION 3-Day Aurora Forecast model: 3-hour cadence

This Aurora 3-Day prediction image is updated every 30 minutes and every time it is refreshed!

http://www.swpc.noaa.gov/node/114

The 3-Day Aurora Forecast model shows the intensity and location of the aurora as expected for the time shown at the top of the map. This forecast is based on the 0 - 3 day forecast of the planetary geomagnetic activity index, Kp, that is provided as input on a 3-hour cadence. Each frame shows the estimated location of the aurora for a three-hour period. The sunlit side of Earth is indicated by the lighter blue of the ocean and lighter color of the continents. The day-night line or terminator is shown as a region that goes from light to dark. The lighter edge is where the sun is just at the horizon. The darker edge is where the sun is 12 degrees below the horizon.
