We report kinematic properties of slow interplanetary coronal mass ejections (ICMEs) identified by SOHO/LASCO, interplanetary scintillation, and in situ observations and propose a modified equation for the ICME motion. We identified seven ICMEs between 2010 and 2011 and compared them with 39 events reported in our previous work. We examined 15 fast (V SOHO−V bg>500 km s−1), 25 moderate (0 km s−1≤V SOHO−V bg≤500 km s−1), and 6 slow (V SOHO−V bg2300 km s−1.Epub 2014 Jan 23
