The present state-of-the-art space and ground-based instrumentation provides us with unprecedented observations of the solar atmosphere from the photosphere to the corona and the heliosphere. Various transient phenomena were identified in the past decade which are believed to play an essential role in the generation of the fast and slow solar wind, e.g. Spicules, EUV/X-ray jets, polar plumes, active region outflows, mini-CMEs (coronal mass ejections) etc. The physical mechanism which generates these phenomena remains unknown though magnetic reconnection is believed to be one of the most likely candidates. The session will critically address the question on whether these phenomena are indeed some of the sources of the solar wind either slow or/and fast, and if so how their contribution can be evaluated and detected at far away distances in the Heliosphere. Relation to small-scale Interplanetary coronal mass ejections (ICMEs) will be discussed.
