We study a quiet-Sun blowout jet which is observed on 2014 May 16 by theinstruments on board Solar Dynamics Observatory (SDO). We find the twin CME asjet-like and bubble-like CME simultaneously as observed by LASCO C2 on boardSolar and Heliospheric Observatory (SoHO), Solar Terrestrial RelationObservatory (STEREO A and STEREO B/COR2). They are respectively associated withthe eruption of the northern and southern sections of the filament. A circularfilament is rooted at the internetwork region at the base of the blowout jet.The collective magnetic cancellation is observed by SDO/HMI line of sight (LOS)magnetograms at the northern end of the filament, which makes this filamentunstable and further makes it to erupt in two different stages. In the firststage, northern section of the filament is ejected, and causes an evolution ofthe northern part of the blowout jet. This part of the blowout jet is furtherextended as a collimated plasma beam to form a jet-like CME. We also observethe plasma blobs at the northern edge of the blowout jet resulting fromKelvin-Helmholtz (K-H) instability in its twisted magneto-plasma spire. In thesecond stage, southern section of the filament erupts in form ofdeformed/twisted magnetic flux rope which forms the southern part of theblowout jet. This eruption is most likely caused by the eruption of thenorthern section of filament, which removes the confined magnetic field of thesouthern section of the filament. Alternative scenarios may be a magneticimplosion between these magnetic structures confined in a much larger magneticdomain. This eruption of southern section of the filament further results inthe bubble-like CME in the outer corona.
