A micro coronal mass ejection associated blowout extreme-ultraviolet jet

Abstract

The so-called mini coronal mass ejections (CMEs) were recently identified as small-scale eruptive events showing the same on-disk characteristics as large-scale CMEs, and Moore etal. further found that one-third of polar X-ray jets are the so-called blowout jets, in which the jet-base magnetic arch, often carrying a filament, undergoes a miniature version of the blowout eruptions that produce major CMEs. By means of the two viewpoint observations from the Solar Dynamics Observatory (SDO) and the Ahead of Solar Terrestrial Relations Observatory (STEREO A), in this Letter, we present the first observations that a blowout jet from the eruption of an EUV mini-filament channel in the quiet Sun was indeed associated with a real micro-CME. Captured by the on-disk SDO observations, the whole life of the mini-filament channel, from the formation to eruption, was associated with convergences and cancellations of opposite-polarity magnetic flux in the photosphere, and its eruption was accompanied by a small flare-like brightening, a small corona dimming, and posteruptive loops. The near-limb counterpart of the eruption observed by STEREO A, however, showed up as a small EUV jet followed by a white-light jet. These observations not only confirm the previous results that mini-filaments have characteristics common to large-scale ones, but also give clear evidences that blowout jets can result from the eruptions of mini-filaments and are associated with mini-CME. © 2011.
