notes

These plots provide an estimate of the location, extent, and intensity of auroral activity on a global basis. Regions under the yellow, orange or red areas have a higher likelyhood of experiencing visible aurora.

The red arrow in the plot points to local noon.

The aurora activity level (listed to the left of the plot) is a general indication of how far from the magnetic pole aurora may be visible:

 activity level   visible at magnetic latitude 
1 67.5
2 66.5
3 65.6
4 63.9
5 62.5
6 60.7
7 58.6
8 56.7
9 54.6
10 51.0
10+ 48.5
10++ 45.0

Magnetic latitude is analogous to normal latitude, except the 90° point is the magnetic pole instead of the actual pole. The magnetic latitude for several cites is as follows:

 north america     europe & asia     southern hemisphere 
 Atlanta   44.5     Athens   31.3     Adelaide   45.9 
 Boston  51.7    Beijing  34.1    Asuncion  16.0
 Chicago  52.2    Berlin  48.3    Buenos Aries  23.3
 Dallas  42.7    Copenhagen  51.9    Canberra  45.0
 Denver  48.3    Edinburgh  53.0    Capetown  41.5
 Havana  34.1    Irkutsk  47.0    Christchurch  49.9
 Los Angeles  39.8    London  47.5    Durban  38.8
 Mexico City  29.1    Madrid  33.3    Harare  29.0
 Minneapolis  55.1    Moscow  51.8    Jakarta  15.0
 Montreal  55.0    Paris  44.2    La Paz  5.0
 New York  50.6    Prague  45.5    Melbourne  48.4
 San Francisco  42.5    Rome  35.5    Montevideo  25.0
 Seattle  52.7    Seoul  31.0    Perth  43.9
 St. Louis  49.2    St. Petersburg  56.1    Punta Arenas  38.6
 Toronto  53.9    Tokyo  29.0    Santiago  20.0
 Washington D.C.  49.1    Vladivostok  36.5    Sydney  43.5
 Winnipeg  59.5    Warsaw  46.7    Wellington  48.0

Auroral activity does not have to reach all the way to your magnetic latitude to be visible. Aurora as much as 5° polewards from your location can usually be seen.

The statistical pattern depicting the auroral oval is determined from the power flux observed during the most recent polar satellite pass. The power fluxes in the statistical pattern are color coded on a scale from 0 to 10 ergs/cm2/sec according to the color bar on the right.

The pattern has been oriented with respect to the underlying geographic map using the current universal time, updated every ten minutes.
