Cosmic Ray Latitude Survey: 1995-1996

During the 1995-96 austral summer, a period of solar minimum, we operated a
neutron monitor on board the ship Italica of the Italian Antarctic Programme to
record cosmic ray neutron intensities in seas from Italy to Antarctica and
back. This survey provided a full coverage of cut-off rigidities and the
possibility of repeating the measurements at least twice at the same cut-offs.
In spite of some problems encountered, mainly due to the unstable AC voltage
supplied by the ship, it was possible to get a preliminary latitude curve of
the cosmic ray nucleonic intensity . Data corrections for efficiency changes,
pressure variations and small primary cosmic ray variations were applied to the
raw data recorded along the survey.
