Operation and Application of High-Resolution Full-Disk Global H-alpha Network

自2000年以来，大熊太阳天文台（BBSO）团队已经运行了一个高分辨率的全圆盘全球H-alpha网络，由五个国家的六个站点组成，全天候监测太阳活动。这些观测站分别位于北京天文台、中国的云南天文台和怀柔太阳观测站、奥地利的坎泽尔河太阳观测站、意大利的卡塔尼亚天体物理观测站和法国的默东天文台。名义上，每个站每分钟以1弧秒的分辨率获得H-alpha图像。PI和他的团队建议继续运行这个网络，以便为太阳-地球社区提供有价值的数据，并对太阳灯丝，耀斑和日冕物质抛射（cme）进行研究。除了为世界各地的太阳和空间科学界提供有价值的数据集外，研究小组还将开展一些项目，以提高我们对空间天气核心组成部分的理解。提出的任务包括利用BBSO全球网络的h - α数据自动检测长丝爆发和耀斑，并跟踪“双带状耀斑”的带状运动，以研究活动区域的非电位、长丝加速度和磁重联率之间的关系。PI的团队还打算将网络H-alpha数据与迈克尔逊多普勒成像仪（MDI）和全球振荡网络组（GONG）的全磁盘磁图结合起来，分析喷发细丝和覆盖拱顶的磁结构，并将这些结果与高级成分探测器（ACE）磁强计数据得出的行星际磁云结构进行比较。PI将结合网络H-alpha数据和Reuven Ramaty高能太阳光谱成像仪（RHESSI）硬x射线数据对微耀斑和耀斑进行统计研究，并将继续研究长丝的大振幅、长周期振荡，以了解控制观测到的振荡的激励、阻尼和恢复力及其与长丝喷发的可能关系。

Since 2000, the Big Bear Solar Observatory (BBSO) team has operated a high resolution full-disk global H-alpha network, consisting of six stations in five countries, to monitor solar activity round-the-clock. The stations are located at BBSO, Yunnan Astronomical Observatory (YNAO) and Huairou Solar Observing Station (HSOS) in China, Kanzelhohe Solar Observatory (KSO) in Austria, Catania Astrophysical Observatory (CAO) in Italy, and Meudon Observatory in France. Nominally, each station obtains H-alpha images every minute with 1 arcsec resolution. The PI and his team proposes to continue operating this network in order to provide valuable data to the solar-terrestrial community and to carry out research on solar filaments, flares, and coronal mass ejections (CMEs). In addition to providing valuable data sets to the solar and space science community around the world, the research team will carry out projects that will improve our understanding of the core components of space weather.Proposed tasks include the automatic detection of filament eruptions and flares and the tracking of ribbon motions of 'two-ribbon flares' using H-alpha data from the BBSO global network, in order to study the relationship among the non-potentiality of active regions, filament acceleration, and magnetic reconnection rate. The PI's team also intends to combine network H-alpha data with Michelson Doppler Imager (MDI) and Global Oscillation Network Group (GONG) full-disk magnetograms to analyze the magnetic configuration of erupting filaments and overlying arcades, comparing those results to the structure of interplanetary magnetic clouds as derived from Advanced Composition Explorer (ACE) magnetometer data. The PI will combine network H-alpha data with Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) hard X-ray data to carry out statistical studies of micro-flares and flares, and will continue to study large amplitude, long period oscillations of filaments in order to understand the excitation, damping, and restoring forces controlling the observed oscillations and their possible relationship to the eruption of filaments.
