Observations of Ultra-Heavy galactic cosmic rays (GCR) help to distinguish the possible origins of GCRs. The Trans-Iron Galactic Element Recorder (TIGER) measures the charge ( ) and energy of GCRs using a combination of scintillation counters, Cherenkov counters, and a scintillating ber hodoscope. TIGER has accumulated data on two successful ights from McMurdo, Antarctica: the rst launched in December of 2001 with a total ight duration of 31.8 days and the second in December of 2003 with a total ight duration of 18 days. We present a preliminary analysis of the combined data from both ights for Ultra-Heavy GCRs. 1.
