General Thoughts / Observations
With an easy launch, the balloon rose steadily and reached float in 4 hours. It went north through Florida, briefly floated over Georgia, then headed off shore. It floated northeast, paralleling the east coast along side Georgia, South Carolina, and North Carolina. It stayed about 25 to 35 miles off coast until turning more eastward and heading out to sea.
This flight was a good demonstration of night and day floats. There were two occasions of erroneous GPS data which caused the AVR to think it was in a dead zone and pause for two hours.
Thoughts for next time
Consider revising the configuration for a reduced dead zone pause. Battery life has not become an issue so there is no reason to sacrifice data over it.
