The omnipresence of transient fluctuations in the solar wind, such as scale magnetic flux ropes (SMFRs), has been well observed by the in-situ observation of Parker Solar Probe (PSP), yet their sources are not clear. Some widely discussed candidates of the solar transient event to drive a perturbation in the solar wind includes the coronal jets and mini-filament (MF) eruptions, which may not be independent of each other. Using the full disk EUV images from Atmospheric Imaging Assembly onboard Solar Dynamic Observatory (SDO/AIA) and H-alpha blue-wing images in Big Bear Solar Observatory (BBSO), we statistically studied the occurrence of coronal ejections and mini-filament and suggested the small-scale ejections from the solar surface to be possible candidates of the SMFRs. Meanwhile, we observed the mini-filament eruptions in the calculated source region of solar wind probed by PSP using high-resolution observations from Goode Solar Telescope (GST) and compare them to the SMFR.
