The public event display of the Pierre Auger Observatory is hosted at the Colorado State University. (Please note that it does take a while to to load up)
The Pierre Auger Collaboration agreed on making 1% of its data available to the public. The Colorado State University website allows browsing over the events collected since 2004, and is updated daily. You can enter an event Id in the search window, search for an event with the event selection menu, or display an event already in cache. You can also download an ascii file with all events.
