We analyze the eruption of a coronal plasma channel (CPC) and an overlyingflux rope using \textit{Atmospheric Imaging Assembly/Solar Dynamic Observatory}(AIA/SDO) and \textit{Solar TErrestrial RElations Observatory} (STEREO)-Aspacecraft data. The CPC erupted first with its low and very faint coronalsignature. Later, above the CPC, a diffuse and thin flux rope also developedand erupted. The spreading CPC further triggered a rotating jet-like structurefrom the coronal hole lying to its northward end. This jet-like eruption mayhave evolved due to the interaction between spreading CPC and the open fieldlines of the coronal hole lying towards its northward foot-point. The CPCconnected two small trans-equatorial coronal holes lying respectively in thenorthern and southern hemisphere on either side of the Equator. These eruptionswere collectively associated with the stealth-type CMEs and CME associated witha jet-like eruption. The source region of the stealth CMEs lay between twocoronal holes connected by a coronal plasma channel. Another CME was alsoassociated with a jet-like eruption that occurred from the coronal hole in thenorthern hemisphere. These CMEs evolved without any low coronal signature andyet were responsible for the third strongest geomagnetic storm of Solar cycle24. These stealth CMEs further merged and collectively passed through theinterplanetary space. The compound CME further produced an intense geomagneticstorm (GMS) with Dst index= -176 nT. The $z$-component of the interplanetarymagnetic field [$B_{z}$] switched to negative (-18 nT) during this interaction,and simultaneous measurement of the disturbance in the Earth's magnetic field(Kp=7) indicates the onset of the geomagnetic storm.
