LCO爆发天体关键（LOOK）项目使用拉斯昆布雷斯天文台（LCO）网络的望远镜来（1）系统地监测先前在整个天空中发现的样本，以评估这些来自早期太阳系的遥远遗迹的演化状态，以及（2）利用现有天空调查的警报来快速响应和描述所有小天体中检测到的爆发活动。收集的爆发数据有助于描述每次爆发随时间的演变，有助于评估一般爆发的频率和震级分布，并有助于了解太阳系中的爆发过程和挥发物分布。 LOOK 项目利用了当前和未来的广域巡天（例如 ZTF、Pan-STARRS 和 LSST）以及快速响应望远镜网络（例如 LCO）之间的协同作用，并作为鲁宾天文台大量天体所需的优秀测试平台。我们将描述 LOOK 项目的目标、规划和目标选择（包括使用 NEOexchange 作为目标和观测管理器或“TOM”）以及第一阶段观测的结果，包括检测巨型彗星 C/2014 UN271（贝尔纳迪内利-伯恩斯坦）上的活动和爆发以及发现和跟踪 14 颗彗星上的 28 次爆发。在这些爆发发现中，我们提出了 7P/Pons-Winnecke 的高节奏光变曲线，在 90 天内观察到了 10 次爆发，57P/duToit-Neujmin-Delporte 上有一次大规模爆发，并有证据表明彗星 P/2020 X1 (ATLAS) 在发现时就处于爆发状态。
The LCO Outbursting Objects Key (LOOK) Project uses the telescopes of the Las Cumbres Observatory (LCO) Network to (1) systematically monitor a sample of previously discovered over the whole sky, to assess the evolutionary state of these distant remnants from the early solar system, and (2) use alerts from existing sky surveys to rapidly respond to and characterize detected outburst activity in all small bodies. The data gathered on outbursts helps to characterize each outburst’s evolution with time, helps to assess the frequency and magnitude distribution of outbursts in general, and contributes to the understanding of outburst processes and volatile distribution in the solar system. The LOOK Project exploits the synergy between current and future wide-field surveys such as ZTF, Pan-STARRS, and LSST, as well as rapid-response telescope networks such as LCO, and serves as an excellent test bed for what will be needed for the much larger number of objects coming from Rubin Observatory. We will describe the LOOK Project goals, the planning and target selection (including the use of NEOexchange as a Target and Observation Manager or “TOM”), and results from the first phase of observations, including the detection of activity and outbursts on the giant comet C/2014 UN271 (Bernardinelli–Bernstein) and the discovery and follow-up of 28 outbursts on 14 comets. Within these outburst discoveries, we present a high-cadence light curve of 7P/Pons–Winnecke with 10 outbursts observed over 90 days, a large outburst on 57P/duToit–Neujmin–Delporte, and evidence that comet P/2020 X1 (ATLAS) was in outburst when discovered.
