  Accelerator Mass Spectrometry (AMS) for measuring concentrations of the l
 ong-lived radionuclides 10Be\, 26Al\, 53Mn and 60Fe in two marine sediment
  cores from the Indian Ocean to search for a signal of a recent supernova 
 explosion ~2 Myr ago close to the solar system. In contrast to 60Fe\, whic
 h is not produced in-situ on Earth\, cosmogenic production of 26Al and 53M
 n in the atmosphere and in-situ adds to a potential extraterrestrial signa
 l. The cosmogenic isotope 10Be\, produced from cosmic rays in the Earth’
 s atmosphere\, is analysed for dating purposes. Our first measurement resu
 lts for 10Be and 26Al will be presented and discussed.
