The Cellar could win $40,000

The challenge is to locate ten moored red weather balloons located at ten fixed locations in the continental United States. Balloons will be in readily accessible locations, visible from nearby roadways and accompanied by DARPA representatives. All balloons are scheduled to go on display at all locations at 10:00AM (ET) until approximately 4:00 PM (local time) on Saturday, December 5, 2009. Should weather or technical difficulties arise with the launch, the display will be delayed until Sunday, December 6 or later, depending on conditions. If, for any reason, the balloon is displayed in one location then moved to a second location, either location will be accepted. Entrants are required to register and submit entries on the event website. Latitudes and longitudes are entered in degree-minute-second (DDD-MM-SS) format as explained on the website Coordinates must be entered with an error of less than one arc-minute to be accepted. In the event that one or more balloons is never displayed, this fact will be noted on the event website and the rules adjusted accordingly.

In the event that no entry containing ten correct locations is received during the contest period, DARPA will determine the entry with the largest number of correct entries. If the largest number is five or greater, the first entrant who submitted this number will be awarded the prize. No prize will be awarded for submission of fewer than five correct sets of locations.

DARPA will issue one check only, and only to the one individual registered on the event website.
