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.

大多数对太阳的研究都需要随着时间的推移进行观察。 因此，世界各地设立了各种监测站来研究不同时间尺度的太阳现象。 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“太阳塔”望远镜。 在过去 23 年里，几乎每个晴天都使用该设施来研究太阳表面的大中尺度速度和磁性特征。 此外，它的姊妹塔 90 英尺高，每天都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，该管理局对太阳耀斑事件进行预测并评估其对地球磁层的影响。 首席研究员 (PI) 建议在未来三年内继续进行这些观察。 在新的资助期内，将发射各种大型太阳能项目或航天器，例如太阳轨道太阳天文台、“MAX 91”太阳活动最大活动以及全球振荡网络组网络，该网络将利用太阳振荡来推断太阳的内部旋转和密度结构。 威尔逊山观测将通过提供广泛、均匀的太阳表面磁活动和气流数据集，在每个晴天直接支持这些企业。
