DIRECD 日冕物质抛射方向目录：基于日冕暗化推断的三维传播

本文介绍了 DIRECD 日冕物质抛射（CME）方向目录，该目录利用 SDO/AIA 211 Å 波段的日冕暗化观测，通过 DIRECD 方法重构了 CME 的三维传播方向。统计分析表明，低日冕中 CME 的传播存在系统性不对称，其轨迹主要受活动区局部磁拓扑结构的影响。

arXiv:2608.20908v1 Announce Type: new Abstract: Coronal mass ejections (CMEs) are among the primary drivers of space weather disturbances at Earth, yet their early propagation in the low corona remains poorly constrained owing to occultation and projection effects inherent to coronagraph observations. Coronal dimmings offer an alternative diagnostic to infer CME propagation direction directly from the low corona. We present the DIRECD CME Direction Catalog, a unified dataset of three-dimensional CME propagation directions derived via the DIRECD (Dimming Inferred Estimation of CME Direction) method, which reconstructs CME cone geometry from SDO/AIA 211 \AA\ coronal dimming observations. The catalog comprises 64 events spanning 2010-2026, combining 31 Solar Cycle 25 (2021-2026) events with 33 events from prior studies. For each event we report the 3D propagation direction, 2D inclination angles, angular width, and cone height. Statistical analysis reveals a systematic asymmetry in low-coronal CME propagation: meridional inclinations exhibit a systematic tendency toward latitude-dependent deflection, with poleward deflections more pronounced at higher source latitudes, while equatorial inclinations show no significant dependence on source longitude. This is consistent with low-coronal CME trajectories being governed primarily by local active-region magnetic topology, with the large-scale coronal field and heliospheric current sheet assuming a progressively dominant role at
