This flight was a real test of patience for everyone! Arriving at the site we encountered thick fog with visibility less than 1/4 mile. Since our FAA waiver requires 5 mile visibiltiy to launch, we had to delay our 0700 launch. The NWS forcast indicated that the fog would lift by 0900. At that time the fog was just as thick as before. We called the FAA and asked if we could launch later in the day. They said any time after 1130 would be acceptable. Payloads were powered down and everyone scattered for breakfast. At 1130 visibility was still minimal, maybe 1/2 mile. We decided to wait until 1230 to start balloon fill for a maximum 1300 launch. At 1230 a decision was made to wait until 1300, then 1315, then 1330. Between 1315 and 1330 the sky brightened and visibility improved. At 1345 visibility was verified to exceed 5 miles and the balloon fill commenced. Launch occured at 1358 with cheers all around.
The flight followed the prediciton reasonably well and landed south of Brush Colorado within 100 meters of the road. The landowner was easily contacted and agreed to retrieval from their property. All student teams were able to retrieve their payloads and were happy with the initial results.

EOSS-218 is a GO for 0700 launch from Eaton Middle School on Saturday, Feburary 13th. The predicted path is shown here.Remember: final masses are due by noon Friday.Tracking information: you can view various tracking links here. If you would like to follow the flight from your smart-phone or tablet (in the car while tracking or at home on your sofa) you can follow the balloon at www.aprs.fi/AE0SS-13 <--correction! (that is a zero). Maps and altitude plots will be posted to this web page after the flight.EOSS-218 will fly a University of Colorado Boulder HDTV signal monitoring experiment and several payloads in support of schools with programs in Science, Technology, Engineering and Math (STEM).

Payload check-in: 0545
Launch time: 0700
Flight path predictions are available here. Scroll down to the flight, date, and anticipated launch site. Click on the GIF link to the right to see a prediction map. Initially the prediction is based on the average winds over 30 years (1981-2010). Starting 15 days before the flight the prediction will be based on the National Weather Service prediction models and will be updated daily. Higher confidence is given to predictions within 3 days of launch, with discussion and final determination of the launch site occurring at that time.
