STEREO-B 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.

概要（或称卡林顿）图的PNG图像，是总结短期与长期日冕演化的高效手段。本数据集包含来自Cor1与Cor2日冕仪的东、西边缘图，HI1/2-A（HI1/2-B）成像仪对应的东（西）边缘图，以及极紫外成像望远镜（EUVI）的中央子午面图。自日地关系天文台（STEREO）任务启动以来，每一次卡林顿自转对应的此类图像均已提供。这些图展现了日冕从相对简单的两扇区结构，逐步演变为愈发复杂的多扇区结构的过程。边缘图中可见的冕流带畸变与不连续性，与太阳活动区、电流片形态以及日冕物质抛射存在关联。极紫外成像望远镜的子午面图则展示了对应的太阳低层大气结构与长期变化。
