This award continues support for a cooperative program of round- the-clock joint observations of solar magnetic fields by the Big Bear Solar Observatory and the Huairou Solar Observing Station of Beijing Observatory. The observations will target the long-term evolution of solar magnetic fields. Particular problems to be addressed will be the polar rotation rate, the evolution of polar field elements, the evolution of active regions, the field changes associated with solar flares, and the flow of magnetic field elements across filament boundaries. This work must be done with China because Huairou has the only other videomagnetograph that operates regularly. The joint observing capability of the two observatories provides a powerful resource. No other solar observatories maintain regular or semi- continuous observations of magnetic fields. Magnetic fields are important to understanding the functioning of the sun and its effect on Earth.

该奖项继续支持大熊太阳观测站与北京天文台怀柔太阳观测站全天候太阳磁场联合观测合作项目。 观测将针对太阳磁场的长期演化。 要解决的具体问题包括极地旋转速率、极场元素的演化、活动区域的演化、与太阳耀斑相关的场变化以及磁场元素穿过细丝边界的流动。 这项工作必须与中国一起完成，因为怀柔拥有唯一一个定期运行的磁像仪。 两个天文台的联合观测能力提供了强大的资源。 没有其他太阳观测站能够定期或半连续地观测磁场。 磁场对于了解太阳的运作及其对地球的影响非常重要。
