Space Weather Predictions at Big Bear Solar Observatory

摘要：ATM 00- 76602提案标题：大熊太阳观测站的空间天气预报首席研究员：王海民，NJIT研究人员将使用大熊太阳观测站（加州）和怀柔太阳观测站（中国）矢量磁像仪测量光球磁场的剪切特性。主要的努力是从获得的数据中获得剪切特性，并使信息在网站上广泛提供，用作耀斑预报。调查人员还将建立一个24小时高分辨率和高节奏的网络（加州、中国、奥地利），在H-α谱线上观测太阳，发展对通量出现和盘上灯丝爆发的自动监测。这些结果还将在一个网站上提供，用于空间气象预报。该网络还将用于改进经典的“空头警报”，使其更加完整。这三个站点中的任何一个都能够启动警报-产生超过80%的占空比。调查将包括对暗条爆发和观测到的地磁暴之间关系的统计研究，以及将观测结果与一个特定的（Chen CME）模型进行比较。

Abstract: ATM 00-76602Proposal Title: Space Weather Predictions at Big Bear Solar ObservatoryPrincipal Investigator: Haimin Wang, NJIT The investigators will use Big Bear Solar Observatory (California) and the Huairou Solar Observatory (China) vector magnetographs to measure shear properties of the photospheric magnetic field. The main effort is to derive the shear properties from data acquired, and to make the information widely available on a web site for use as a flare predictor. The investigators will also implement a 24-hour high-resolution and high-cadence network (California, China, Austria) to observe the Sun in the spectral line H-alpha, developing automatic monitoring for flux emergence and on-disk filament eruptions. These results will also be made available on a web site for use in space weather forecasting. This network will also be used to improve the classic "Bear Alerts" and make them more complete. Any of the three stations will be able to initiate an alert - yielding a duty cycle over 80%. The investigation will include a statistical study of the relation between filament eruptions and observed geomagnetic storms, and comparison of observations with a specific (Chen CME) model.
