Heliospheric Observation of Earth - Directed Interplanetary Coronal Mass Ejection in 2008 - 2014

The relation between interplanetary coronal mass ejection (ICMEs) morphology and variety of phenomena occurring in the low corona, is still an open issue. Generally assumption is that all ICMEs have a flux rope structure, but some observational analyses shows that on average only one-third of detected ICMEs show clear magnetic cloud (MC) signature. Futhermore, existence of so-called stealth coronal mass ejection whose not exhibit any obvious low-corona signatures, clearly indicate necessity to upgrades of the theoretical ICME models. In this work we presented an online catalogue for general use of the Earth and near-Earth directed single ICMEs (ICMEs interaction are excluded) in the period from January 2008 to September 2014, with additional data of corresponding solar wind disturbance. ICMEs data are gathered from the Solar Terrestrial Relations Observatory (STEREO), Solar Dynamic Observatory (SDO) and Solar and Heliospheric Observatory (SOHO), although in situ data about solar wind are used from WIND satellite. For all ICMEs we calculated kinematics parameters and for corresponding disturbances we made a detailed analysis of the in situ data. We separated the ICMEs in different types, regarding on their connections with low-corona signatures (especially: active region, prominence and flare). Our analysis shows that MC/flux rope structure is not recognised for ICMEs whose origin is not connected with obvious low-corona signatures.
