Description
EUSO-Balloon is a pathfinder mission for the Extreme Universe Space
Observatory onboard the Japanese Experiment Module (JEM-EUSO). It was
launched on the moonless night of the 25th of August 2014
from Timmins, Canada. The flight ended successfully after maintaining
the target altitude of 38 km for five hours. One part of the mission was
a 2.5 hour underflight using a helicopter equipped with three UV light
sources (LED, xenon flasher and laser) to perform an inflight
calibration and examine the detectors capability to measure tracks
moving at the speed of light. We describe the helicopter laser system
and details of the underflight as well as how the laser tracks were
recorded and found in the data. These are the first recorded laser
tracks measured from a fluorescence detector looking down on the
atmosphere. Finally, we present a first reconstruction of the direction
of the laser tracks relative to the detector.
