The minimum phase of solar cycle 23 and the ascendent phase of solar cycle 24 were optimal periods for the detection of mesoscale structures in white-light (WL). Blobs are a subset of these structures and considered to be tracers of the slow solar wind. In this work, we present a kinematic analysis of blobs’ deprojected 3D trajectories using a height-time analysis and data from SOHO/LASCO and STEREO/SECCHI coronagraphs. We will explore their dynamics through a ‘drag-force’ model and identify their origin using a 3D Potential Field Source Surface (PFSS) model in the inner corona.
