The investigators will conduct an extensive program of solar physics research at Big Bear Solar Observatory (BBSO) through the maximum of solar cycle 23. The main effort is to make synoptic, calibrated, comprehensive, and continuous observations of the whole sun at the highest possible resolution and cadence, as well as to come to a scientific understanding of the implications of the data obtained. The research plan emphasizes high resolution and high cadence studies of solar activity and magnetic fields. New Jersey Institute of Technology (NJIT) took over operation of BBSO on July 1, 1997. Since that time, the observatory has undergone fundamental changes marked by significant achievements in science, instrumentation and education. The investigators have solved the long-standing dome seeing problems at BBSO, so that the observatory is now one of only two observatories in the US capable of high-resolution observations of the sun. They will use the new capability to conduct sub-arc second resolution studies of active regions and the quiet sun including comprehensive studies of vector magnetic fields in flare-producing active regions. They will also develop and deploy new instruments and facilities, such as a new generation vector magnetograph system employing state-of-the-art digital cameras, a parallel computing system for real-time speckle reconstruction, and near infrared magnetograph and imaging systems. These will employ a unique, narrow band Lyot filter and an infrared Fabry-Perot filter. As a service to the community, they will also continue the successful BBSO Activity Reports and Warnings (www.bbso.njit.edu/cgi-bin/ActivityReport), and make daily full-disk data and data from the 25 cm telescope available by anonymous ftp (ftp.bbso.njit.edu).

研究人员将在大熊太阳天文台（BBSO）进行广泛的太阳物理研究计划，直到太阳活动周期23的最大值。主要的努力是以尽可能高的分辨率和节奏对整个太阳进行天气学的、校准的、全面的和连续的观测，以及对所获得的数据的含义进行科学的理解。该研究计划强调对太阳活动和磁场进行高分辨率和高节奏的研究。1997年7月1日，新泽西理工学院（NJIT）接管了BBSO的运营。从那时起，天文台经历了根本性的变化，标志着在科学，仪器和教育方面取得了重大成就。研究人员已经解决了BBSO长期存在的圆顶观测问题，因此该天文台现在是美国仅有的两个能够高分辨率观测太阳的天文台之一。他们将利用这一新能力对活动区和平静太阳进行亚弧秒分辨率研究，包括对产生耀斑的活动区矢量磁场进行全面研究。他们还将开发和部署新的仪器和设施，例如采用最先进的数码相机的新一代矢量磁像仪系统，用于实时斑点重建的并行计算系统，以及近红外磁像仪和成像系统。这些将采用独特的窄带Lyot滤波器和红外法布里-珀罗滤波器。作为对社区的一项服务，他们还将继续成功的BBSO活动报告和活动报告（www.bbso.njit.edu/cgi-bin/ActivityReport），并通过匿名FTP（ftp.bbso.njit.edu）提供每日全磁盘数据和来自25厘米望远镜的数据。
