Synoptic Studies of Solar Velocity and Magnetic Fields Using the 150-foot Solar Tower on Mt. Wilson

大多数对太阳的研究都需要随着时间的推移进行观测。因此，世界各地设立了各种监测站，以研究各种时间尺度上的太阳现象。美国太阳观测的一个重要来源是位于加利福尼亚州威尔逊山的150英尺高的“太阳塔”望远镜。在过去的23年里，这个设备几乎在每个晴朗的日子里都被用来研究大中型太阳表面的速度和磁场特征。此外，它的姊妹塔高90英尺，每天都被用来绘制太阳黑子图。这些图纸被传送给国家海洋和大气管理局，该机构对太阳耀斑事件进行预测，并评估它们对地球磁层的影响。首席调查员(PI)建议在未来三年内继续进行这些观察。在新的赠款期间，将推出各种大型太阳项目或航天器，例如太阳轨道太阳观测站、“MAX 91”太阳活动最大运动和全球振荡网络小组网络，该网络将利用太阳振荡来推断太阳的内部自转和密度结构。这座山。威尔逊观测将在每个晴朗的日子通过提供太阳表面磁活动和气体流动的广泛、均匀的数据集，直接支持这些企业。

Most studies of the Sun require observations over time. Thus a variety of monitoring stations have been set around the world to study solar phenomena on a variety of timescales. An important source of solar observations in the U.S. is the 150-foot "solar tower" telescope, located on Mount Wilson in California. This facility has been used on virtually every clear day for the last 23 years to study large and medium scale velocity and magnetic features on the surface of the Sun. In addition, its sister 90- foot tower is used daily to make sunspot drawings. These drawings are transmitted to the National Oceanic and Atmospheric Administration which make forecasts of solar flare events and assesses their impact on the Earth's magnetosphere. The Principal Investigator (PI) proposes to continue these observations over the next three years. During the new grant period a variety of large solar projects or spacecraft will be launched, such as the Solar Orbiting Helio-Observatory, the "MAX 91" solar-activity maximum campaign, and the Global Oscillation Network Group network, which will utilize solar oscillations to infer the interior rotation and density structure of the Sun. The Mt. Wilson observations will directly support these enterprises every clear day by providing an extensive, homogenous dataset of magnetic activity and gas flows on the solar surface.
