%X On 2015 January 6&-7, an interplanetary coronal mass ejection (ICME) was observed at L1. This event, which can be associated with a weak and slow coronal mass ejection, allows us to discuss the differences between the boundaries of the magnetic cloud and the compositional boundaries. A fast stream from a solar coronal hole
surrounding this ICME offers a unique opportunity to check the boundaries' process definition and to explain
differences between them. Using Wind and ACE data, we perform a complementary analysis involving
compositional, magnetic, and kinematic observations providing relevant information regarding the evolution of the
ICME as travelling away from the Sun. We propose erosion, at least at the front boundary of the ICME, as the main
reason for the difference between the boundaries, and compositional signatures as the most precise diagnostic tool
for the boundaries of ICMEs.
