What are the symbols on the map?

Last Updated: Sep 20, 2014 05:12PM UTC

        Scientist: indicates the location of a space scientist in the Aurorasaurus Scientist Network.

        Positive sighting: A green plus indicates that a citizen science report was filed by someone who saw the aurora. If many sightings are clustered on the map, a single, green 10+ circle will appear.

         Negative sighting: A red minus indicates that a citizen science report was filed by someone who looked for the aurora, but did not see it. A cluster of negative reports are indicated by a single, red 10+ circle.

         Unverified tweet: Our twitter feed selected this tweet because it used one of our buzz words, like aurora or northern lights. This tweet cannot be added to the interactive map until multiple users verify that the tweet was actually about a recent observation of the aurora.

         Verified tweet: This tweet references a recent, positive sighting of the aurora that has already been verified by multiple Aurorasaurus users.

         1 Hour Forecast: Satellite data and modeling indicate that the purple region will have the strongest aurora in the next hour. Remember, viewing is only possible at nighttime with cloudless skies.

         Current Oval Estimate: Satellite data and modeling indicate that auroral activity is currently strongest in the pink region. If your region is covered and it is dark outside, go take a look at the sky! Even if you are south of the oval, you may be able to view the aurora. Aurora are sometimes visible from a few hundred miles south of the oval if you look at the northern horizon.
