STEREO-A Carrington Maps for the SECCHI Cor1 Telescope

PNG images of Synoptic (or Carrington) Maps comprise an efficient method to summarize both short term and long term coronal evolution. This resource contains East and West limb maps from the Cor1 and Cor2 coronagraphs, East(West) limb maps for HI1/2-A (HI1/2-B) imagers, and central meridian maps from the EUVI telescope. Maps are available for each Carrington Rotation since the beginning of the STEREO mission. The maps demonstrate the evolution of the corona from a relatively simple, two-sectored structure to an increasingly complex multi-sectored structure. Distortions and discontinuities in the streamer belt visible in the limb maps are associated with active regions on the sun, the shape of the current sheet, and coronal mass ejections. Meridian maps for EUVI illustrate the corresponding structures and long-term changes in the lower atmosphere.

背景概述

该数据集提供了STEREO-A卫星SECCHI Cor1望远镜生成的Carrington图，包含来自日冕仪和极紫外成像仪的多视角边缘图和中央子午线图，覆盖整个STEREO任务期间的每个Carrington自转。这些PNG图像有效展示了日冕从简单两扇区结构向复杂多扇区结构的演变，并能揭示与活动区、电流片及日冕物质抛射相关的高层日冕特征。数据以CC0协议发布，支持太阳物理研究中的长期日冕演化分析。
