Auroral Oval Indicator Plots

Currently generated indicator plots are given in the following list. Plots which are made obsolete by the arrival of new data are deleted automatically, and plots are also deleted after 90 days. If there is no plot for the date in which you interested, you can issue a request to create it using the form below. The plots are Encapsulated Postscript files with names of the form

   YYYY-MM-DD.eps

where YYYY, MM and DD are the year, month and day respectively. The presence of a file with a similar name but having the extension .wip indicates that a plot for that day is currently being generated.

There is currently enough data from December 1995 onwards to make the indicator plots meaningful.

To produce a plot of the Contracted, Normal and Expanded Ovals, select a date using the form below. The indicators are re-calculated if there is new data since the last calculation, so this process may take some time. If you return to this page a few minutes later the plot should be ready.
