Balloon flight B-11, 1 September 2013

Hardware used on this flight is identical to B-10 and B-12. B-11 payload is recovered B-10 with repaired solar panels. Balloon envelope has been replaced before re-launching.

Some significant altitude oscillations (yo-yoing) were seen during initial ascent.

Many trackers have joined to help track the balloon. Remotely controlled receivers were used to receive telemetry. Altogether more than 150 stations have submitted telemetry data and postion reposts.

Big thank you to all of you who helped track the balloon progress!
