- Payloads need to be onsite at 7:00 am for weigh-in and string up
- We will be launching from Eaton MS
Exempt balloon flying several 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 8:30am. See the Payload Plan linked below.
Here is the 24-hour flight prediction. This is one you want to print out and bring with you. This is the most accurate pre-flight prediction. The profile shows a modeled estimation of the flight (you can practice your metric units!).
Here is the 24-hour prediction file for TrackPoint.

TR Breakfast:
Breakfast Location Change!! Due to the change in prediction, Mike has suggested we head for Brush and then go north from there. So the new breakfast site is: Drovers Restaurant
28601 US Hwy 34, Brush CO 80723, 970-842-4218
Due to the later launch time (8:30), breakfast will also be later! See you at 7:00! It appears that this might be in line with the prediction.
Notice to all TRACKERS! We will need to take bearings on this flight, so be prepared on the ascent, to take and report a bearing to Alpha. As a reminder, the reporting process is like this example: "Station Bravo, 32, 45, 239 Degrees True, KØSCC (where Station Bravo is the tactical call, 32 is your X coordinate, 45 is the your Y coordinate, 239 is the bearing from that location, True indicates the true bearing and of course the call.) So lets be prepared. (Scroll Down)
