AbstractWe report the formation of a complicated coronal mass ejection (CME) on 2015 August 23 by using the high temporal and high spatial resolution multi-wavelength observations taken by the Solar Dynamic Observatory and the Solar and Heliospheric Observatory. The CME exhibited both jetlike and bubble-like components simultaneously, and therefore, we call it a twin CME. Detailed imaging and kinematic analysis results indicate that the twin CME was evolved from the eruption of a mini-filament-driven blowout jet at the eastern edge of an equatorial coronal hole, in which the activation of the mini-filament was tightly associated with the continuous flux cancellation and quasi-periodic jetlike activities in the filament channel. Due to the magnetic reconnection between the filament and the ambient open field lines, the filament broke partially at the northern part and resulted in an intriguing blowout jet in the southern direction. It is interesting that the ejecting jet was deflected by a group of remote open field lines, which resulted in the significant direction change of the jet from southward to eastward. Based on the close temporal and spatial relationships among the jet, filament eruption, and the twin CME, we conclude that the jetlike CME should be the coronal extension of the jet plasma, while the bubble-like one should have originated from the eruption of the mini-filament confined by the closed magnetic fields at the jet base.
