This is a practice flight for the August 21, 2017 eclipse. The flight will be launched from Camp Guernsey WY and will be two 1500 gram balloons with Colorado Space Grant eclipse observation payloads. The total solar eclipse will be on August 21, 2017.Launch Time will be 10:45 am and 11 am, rather than the usual crack of dawn launch.Our launch site for this will be inside the north training area of Camp Guernsey. We have obtained special permission to operate there, but please remember that this is a Wyoming National Guard training facility (i.e. military installation). As a military installation there are additional rules, vehicles may be subject to search and inspection. Please treat any military personnel you may encounter with respect, we want to make a good impression on our hosts. Since this is a restricted area, access should be coordinated through the EOSS Flight Coordinator. (Contact info below)Camp Guernsey has allowed us to camp at the launch site. Most of us will be in tents, but RV's are allowed. No open or charcoal fires, but camp stoves up off the ground are permissible. Any generators or fuel needs to have containment (steel or plastic tray underneath to catch spillage and fluids). We will have Porta-Potties on site but no water, so you will need to bring your own. Trash will need to contained within your vehicle since we have no provision at this time. Please, no pets and any smokers dispose of the butts in your vehicle. Camp Guernsey personnel will be inspecting the site before we leave. Please stick to the road once you are on Camp Guernsey property. We have been cleared only for the use of the Connex Village and a couple of specific sites. Other sites have the potential to be environmentally or culturally (archeological) sensitive.
