The New Jersey Institute of Technology (NJIT) has operated Big Bear Solar Observatory (BBSO) since July 1, 1997. This project continues NSF support of that facility, and is motivated by BBSO having reached the final stage in building its 1.6 meter aperture off-axis New Solar Telescope (NST). The NST will become an essential test-bed for the US solar physics community's planned 4-meter Advanced Technology Solar Telescope (ATST).In this project, the PI will complete the integration of the NST's visible and near infrared vector magnetograph systems, as well as the commissioning of the telescope to its full scientific capability. The PI's team will exploit NST observations in the visible and near IR for a variety of solar physics research programs. These NST observations will make possible high-cadence and high-resolution studies of solar flare emissions, sub-arc-second resolution studies of the quiet solar atmosphere (focusing on measurements of the transverse magnetic field component, which is weaker than intra-network fields), investigations of the energy sources of coronal heating, comprehensive studies of vector magnetic fields associated with flares, and investigations of plasma flow fields in flare-productive active regions. BBSO's high quality data and analytical tools are routinely utilized by the space weather forecasting community. BBSO is a leader in the US community for developing the next generation of solar instrumentation and training the next generation of solar physicists. About 30% of NJIT students in this field are women. BBSO is a key part of NJIT's integrated approach to space physics research and education, with graduate student research and dissertation opportunities supported throughout this project.

新泽西理工学院（NJIT）自1997年7月1日起开始运营大熊太阳观测站（BBSO）。该项目继续NSF对该设施的支持，并受到BBSO在建造其1.6米口径离轴新太阳望远镜（NST）方面达到最后阶段的推动。NST将成为美国太阳物理界计划的4米先进技术太阳望远镜（ATST）的重要测试平台。在该项目中，PI将完成NST的可见光和近红外矢量磁像仪系统的集成，以及望远镜的调试，以充分发挥其科学能力。PI的团队将利用NST在可见光和近红外的观测结果进行各种太阳物理研究计划。这些NST观测将使得有可能对太阳耀斑排放进行高节奏和高分辨率的研究，对安静的太阳大气进行亚弧秒分辨率的研究（侧重于横向磁场分量的测量，该分量比网内场弱），日冕加热能源的调查，与耀斑有关的矢量磁场的综合研究，和耀斑活动区等离子体流场的研究。空间气象预报界经常使用BBSO的高质量数据和分析工具。BBSO是美国社区的领导者，致力于开发下一代太阳能仪器和培训下一代太阳物理学家。该领域约30%的NJT学生是女性。BBSO是NJIT空间物理研究和教育综合方法的关键部分，在整个项目中支持研究生研究和论文机会。
