Conclusion Installed a laser to probe the reach of our HE aperture (34 km Distant) Equivalent light production to a shower of ~6x10 19 to eV Detectors have no trouble seeing this laser under good to acceptable viewing conditions. Aerosol optical depth measured by Terra Laser/HiRes2 correlates with that measured by HR2SLS and HiRes1 detector
