EOSS-237 Eaton MS Flight

Exempt balloon flying 5 science experiments on three payloads built by Eaton Middle School students.

There are a mutlitude of links located here that provide weather predictions, weather observations, and during the flight, real time tracking information.

The launch will be at 7:00am. See the Payload Plan linked below.

Here is the 12-day flight prediction. This prediction is expected to change significantly over the next two weeks. The prediction has moved to the southwest. The black circle to the south of the prediction is the DIA Class B air space. We will stay out of that area. Unfortunately, predictions are not online at this time. They can be accessed at this web location. The predictions will be updated on most days.
