标题： Two Cases of Non-Radial Filament Eruption and Associated CME Deflection

摘要： 本文的目的是分析两个宁静暗条爆发的多波长和多仪器观测，以及相关日冕物质抛射（CMEs）相对于径向方向的偏转。 事件分别发生于2017年10月18日和2021年5月9日，位于太阳南半球。 它们及相关的耀斑均被太阳动力学天文台（SDO）上的大气成像仪（AIA）和日地关系天文台-前导（STEREO-A）在不同的极紫外波段记录下来。 利用STEREO A COR1和COR2仪器以及太阳和日球天文台（SOHO）上的大角度光谱日冕仪（LASCO）的数据，我们研究了爆发的形态和运动学特性，以及相关日冕物质抛射相对于爆发暗条的纬度偏移。 我们的观测结果提供了证据，表明这两个暗条爆发具有高度非径向特征。 观察到的偏差归因于低纬度日冕洞的存在。 显示英文摘要

摘要： The purpose of this paper is to analyze the multi-wavelength and multi-instrument observations of two quiescent filament eruptions as well as the deflection of associated CMEs from the radial direction. The events occurred on 18 October 2017 and 9 May 2021, respectively, in the southern solar hemisphere. Both of them and associated flares were registered by the Atmospheric Imaging Assembly (AIA) aboard the Solar Dynamics Observatory (SDO) and the Solar Terrestrial Relations Observatory-Ahead (STEREO-A) Observatory in different EUV wavebands. Using data from STEREO A COR1 and COR2 instruments and the Large Angle and Spectrometric Coronagraph (LASCO) onboard the Solar and Heliospheric Observatory (SOHO), we investigated morphology and kinematics of the eruptions and the latitudinal offset of the related CMEs with respect to the erupting filaments. Our observations provide the evidence that the two filament eruptions were highly non-radial. The observed deviations are attributed to the presence of low-latitude coronal holes.
