So Why protons at 57 EeV?So Why protons at 57 EeV?Why a Super Galactic plane..not longer Why a Super Galactic plane..not longer

mentionedmentionedWhy so many events around Cen A?Why so many events around Cen A?

GZK in agreement with light GZK in agreement with light nucleinuclei

So light nuclei may So light nuclei may trace nearer Universe trace nearer Universe and fit AUGER GZKand fit AUGER GZK

More about z=0.01 More about z=0.01 Universe..Universe..

Where is Virgo?Where is Virgo?

So maybe AUGER confused So maybe AUGER confused SGP with Cen A blurred source?SGP with Cen A blurred source?

So this need a testSo this need a test
