The Catalina Sky Survey is a NASA-funded program to search for moving objects in our solar system. The NSF-supported Catalina Real-Time Transient Survey (CRTS) makes complimentary use of this same data stream to search among the fixed background stars for transient events, like supernovae and other forms of stellar explosions, and to monitor many types of variable sources. It releases its results in real time so that they can be followed up immediately by professional and serious amateur astronomers. The CRTS is developing a new kind of scientific infrastructure: real-time mining of massive data streams coupled with dynamic follow-up strategies. Students have opportunities to participate in hardware or software development, data mining itself, to obtain follow-up observations, and in the scientific analysis of the transient sources. To date, CRTS has discovered over 6500 distinct transient events and over 13 million variable sources. Through both formal and informal collaborations, as well as data sharing with the entire astronomical community, CRTS is enabling studies of variable stars, active galactic nuclei, the explosions that mark the endpoints in the life cycles of stars, stellar flares, cataclysmic variables and recurrent novae, planets around white dwarfs, new counterparts of gamma-ray sources, and many other interesting phenomena observable through "time domain astronomy". This award provides funding for continuation of this highly-successful program as well as for several key enhancements. This program, using existing telescopes and a large data stream, provides a testbed to develop data mining tools and procedures as a precursor to LSST and other missions under development.

Catalina Sky调查是一项由NASA资助的计划，用于在我们的太阳系中寻找移动对象。 NSF支持的Catalina实时瞬态调查（CRT）使该数据流相同的数据流在固定的背景星之间搜索瞬态事件，例如超新星和其他形式的恒星爆炸，并监视许多类型的可变来源。 它可以实时发布结果，以便可以立即进行专业和认真的业余天文学家的跟进。 CRT正在开发一种新型的科学基础架构：大规模数据流的实时挖掘以及动态后续策略。 学生有机会参与硬件或软件开发，数据挖掘，获得后续观察以及对瞬态来源的科学分析。迄今为止，CRT已发现6500多个不同的瞬态事件和1300万多个可变来源。 Through both formal and informal collaborations, as well as data sharing with the entire astronomical community, CRTS is enabling studies of variable stars, active galactic nuclei, the explosions that mark the endpoints in the life cycles of stars, stellar flares, cataclysmic variables and recurrent novae, planets around white dwarfs, new counterparts of gamma-ray sources, and many other interesting phenomena可通过“时域天文学”观察。 该奖项为延续这个高度成功的计划以及几个关键增强功能提供了资金。 该程序使用现有的望远镜和大型数据流，提供了一个测试台，以开发数据挖掘工具和程序作为LSST和其他正在开发的任务的先驱。
