Auger South! Observed the GZK feature in the spectrum! Determined Sky anisotropies > 60 EeV! Showed that the GZK sphere is populated! Strongest UHE tau neutrino and UHE photon limits! Finds a puzzling composition at around 40 EeV - ! Need to measure composition > 60 EeV! PROBLEM: Not Big Enough! Can only detect ! ~ 25 events/yr > 60 EeV with Surface Detector! ~ 2 events/yr > 60 EeV w/ Fluorescence Detector!
Auger North! "7 times bigger "(for 2.3 x $)! Auger North plus South will observe:! 2000 events in 10 yr > 60 EeV with SD! 200 events in 10 yr > 60 EeV with FD!
