Abstract
Recently the AGASA Collaboration presented data suggesting a significant clustering of ultra-high energy cosmic rays coming from the outer Galaxy region. In this paper we calculate expected cosmic ray arrival distributions for several simple, limiting source location scenarios and investigate the possibility of clustering and correlation effects. The role of the Galactic magnetic field is discussed in detail.Comment: 33 pages, 21 figures (5 in color), 2 tableKeywords
