Perhaps you are looking at this page because you found a white sphere with this internet address on it. Or maybe you received our APRS transmission. Project Eos is a project The Bay School of San Francisco’s Atmospheric Science course in which students build and release weather balloons to collect data from the upper atmosphere and take photos like this one, taken from over 98,000 feet on a previous flight:
Here is a link to the official Project Eos webpage.
If you’ve found a tracking device for our weather balloon, hopefully we already be on the way, but please give us a call to help us retrieve our equipment! David: 651 815 2122 or Craig: 415 823 8279.
