Spatial correlations of Si III detections in the local interstellar
  medium
  Since the developpment of astronephography, we know that the Sun is about to
exit the Local Interstellar Cloud (LIC). To date, because of its rare
absorption signatures and the paucity of suitable neighbour targets, the LIC
interface has proved to be elusive to extensive investigations. Comparing the
spatial distribution of Si III detections found in the litterature along with 3
new sigtlines, I show that most detections seem to arise from a cone whose axis
is parallel to the LIC heliocentric velocity vector. I interpret this result as
an evidence that the heliosphere is actually interacting with the LIC frontier.
