GUANO-2  Higher and Higher!

Results

Launching on a wind-less morning meant that the package was successfully tracked for almost 4 hours in total.

As can be seen in the graph at right, data were recorded from the cosmic ray (CR) detector as the balloon rose to just over 35 km (green triangles), then on the way down (purple circles). 

The CR counts increase to about 20 km, then remain approximately constant until about 25 km.  At this height, most of the CRs detected are from secondary particle showers.

Above 26 km, the CR counts begin to decrease as more of the CRs  detected are primary particles and fewer secondary showers have been created.  The first GUANO flight did not show this decrease because it did not go high enough.
