Its 44Ti activity reflects GCR flux integrated since the mid of 1700 to the time of falland confirms the decreasing trend of GCR flux that we previously suggested on the basis of measurements of othermeteorites which fell in the last 250 years as well as the centennial modulation of GCR due to the Gleissberg solarcycle This result was obtained thanks to the high-efficiency and selective configuration of the gamma-ray spectrom-eter (HPGe+NaI) operating at the underground Laboratory of Monte dei Cappuccini (OATo, INAF) in Torino, Italy.
