Recent spectroscopic observations acquired during the total solar eclipses of 2015 and 2017 revealed the presence of filamentary hot coronal material with cool inclusions of neutral (He, H, Fe, Mg) and singly and doubly ionized atoms, most likely associated with CME fronts, streaming away at several 100's to over 1000 km/s. A handful of cases of distinct bright inclusions of prominence material within the filamentary features of a CME front have also been reported in LASCO/C2, C3 and STEREO observations. In-situ measurements of low ionization states of different species at the few percent level within CMEs, have been attributed to prominence material. Observations of low ionized atoms from SOHO/UVCS observations, were attributed to interstellar neutral atoms, or even to neutrals produced by plasma-dust interaction. This session invites contributions from observers and modelers, to explore the possible sources of neutrals and low-ionization plasmas in the corona and interplanetary space.
