STEREO COR1 CME catalog

This catalog is a list of coronal mass ejections (CMEs) observed by the COR1 instrument. COR1 is part of the Solar Terrestrial Relations Observatory (STEREO) mission, composed of twin spacecraft, the Behind-Earth and the Ahead-Earth spacecraft. It is the inner coronagraph of the Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI) suite and has a field of view (FOV) from 1.4 to 4 solar radii. The catalog contains all CMEs manually identified since December 2006, which have width greater than 10 degrees, including faint events that are often missed by auto-detection methods. Events from STEREO-A and B are noted separately. The catalog consists of a set of monthly tables.
Starting from solar cycle (SC) 25, the catalog was updated by including COR2 and LASCO C2 movies and links to in-situ interplanetary CMEs (ICMEs), particle events and type II radio data. Note that, in 2014, contact with STEREO-B was lost after entering an uncontrolled spin preventing its solar panels from generating enough power. After that the catalog contains only STEREO-A events. In addition, there is data gap between 2014 and 2015 for STEREO-A due to its position almost directly behind the sun and it was transmitting only a weak signal or occasionally none. STEREO-A resumed its normal operation in November 2015. The description of the parameters is given in accordance with the order in 2022.

本目录收录了COR1仪器观测到的日冕物质抛射（coronal mass ejections, CME）。COR1是日地关系观测台（Solar Terrestrial Relations Observatory, STEREO）任务的组成载荷，该任务搭载两颗航天器，分别为地球后方轨道器与地球前方轨道器。它是日地连接日冕与日球层探测（Sun Earth Connection Coronal and Heliospheric Investigation, SECCHI）套件的内日冕仪，视场（field of view, FOV）范围为1.4至4倍太阳半径。本目录收录了2006年12月以来人工识别的所有宽度大于10度的CME，其中包含诸多自动探测算法常遗漏的微弱事件。来自STEREO-A与STEREO-B的观测事件将分别标注。本目录以月度表格集的形式呈现。
自第25个太阳周期（solar cycle, SC）起，本目录新增了COR2与LASCO C2的影像数据，以及原位行星际日冕物质抛射（interplanetary CMEs, ICME）、粒子事件与II型射电数据的相关链接。需注意，2014年STEREO-B因进入不受控自旋状态，导致太阳能帆板无法产生足够电力，随后与地面失去联系。自此之后，本目录仅收录STEREO-A的观测事件。此外，2014至2015年间，STEREO-A因位置几乎完全处于太阳后方，仅能传回微弱信号甚至偶尔无法传输数据，存在数据空白期。STEREO-A于2015年11月恢复正常运行。参数说明按照2022年版的编排顺序给出。

背景概述

该数据集是STEREO任务COR1仪器观测的日冕物质抛射（CMEs）目录，包含自2006年12月以来手动识别的所有宽度大于10度的CMEs事件，并以月度表格形式组织。数据集从太阳周期25开始更新，增加了COR2和LASCO C2电影及链接到原位ICMEs等数据，但2014年后仅包含STEREO-A事件，且存在短暂数据缺口。
