9305721 Honeycutt A new telescope will be installed and equipped with advanced instrumentation for automated photometry and spectroscopy. Information on the time variability of astronomical objects is often critical to understanding the nature and evolution of stars and galaxies. This new telescope will provide a way to acquire data on a variety of time scales in an efficient manner that does not require the astronomer's presence at the telescope. This is a new capability for stellar spectroscopy whose feasibility has only recently been demonstrated. The objects to be studied include cataclysmic variable stars (CVs) and active galactic nuclei (AGNs). Members of the CV class include dwarf novae and novae. This new telescope will provide a long-term photometric and spectroscopic monitoring of several kinds of CVs. Such observations bear critically on poorly-understood evolutionary relations between the numerous CV types. The optical variability of AGNs and other kinds of high energy source will also be monitored with the new telescope. These observations will be correlated with measures at other wavelengths and with particle detector experiments. The methods to be employed in this work are charge-coupled-device (CCD) photometry and CCD echelle spectroscopy. The instrumentation will be carefully matched to the telescope and to the detectors to provide optimized sensitivity. The completed telescope will also be used extensively for student training in astronomical research, in astronomical techniques, and in low-light-level instrumentation. ***

小行星9305721 将安装一个新的望远镜，并配备先进的自动测光和光谱仪器。 关于天体时间变化的信息对于理解恒星和星系的性质和演化往往至关重要。 这种新的望远镜将提供一种以有效的方式获取各种时间尺度上的数据的方法，而不需要天文学家在望远镜前。 这是恒星光谱学的一种新能力，其可行性最近才得到证实。 研究对象包括激变变星和活动星系核。 CV类的成员包括矮新星和新星。 这台新望远镜将提供对几种CV的长期光度和光谱监测。 这些观察结果对许多CV类型之间的进化关系知之甚少至关重要。 活动星系核和其他高能源的光学变化也将被新望远镜监测。 这些观测将与其他波长的测量和粒子探测器实验相关联。 在这项工作中所采用的方法是电荷耦合器件（CCD）测光和CCD阶梯光栅光谱。 仪器将与望远镜和探测器仔细匹配，以提供最佳的灵敏度。 完成后的望远镜还将广泛用于天文学研究、天文学技术和微光仪器的学生培训。 ***
