FRB 121102 was the first Fast Radio Burst (FRB) that was shown to repeat. Since its discovery in 2012, more than two hundred bursts have been detected from the source. These bursts exhibit a diverse range of spectral and temporal characteristics and many questions about their origin and form remain unanswered. Here, we present a sample of radio bursts from FRB 121102 detected using the Lovell telescope at Jodrell Bank Observatory. We show four examples of bursts that show peculiar spectro-temporal characteristics and compare them with properties of bursts of FRB 121102 detected at other observatories. We report on a precursor burst that is separated by just 17 ms from the main burst, the shortest reported separation between two individual bursts to date. We also provide access to data for all the detections of FRB 121102 in this campaign.

来自FRB 121102的爆裂样品的光谱时间分析

FRB 121102是第一个重复出现的快速无线电突发（FRB）。自从2012年被发现以来，已从源头检测到200多次爆发。这些爆发表现出各种各样的频谱和时间特征，关于其起源和形式的许多问题仍未得到解答。在这里，我们提供了使用Jodrell Bank天文台的Lovell望远镜检测到的FRB 121102无线电脉冲的样本。我们展示了四个具有特殊光谱时态特征的爆发实例，并将它们与在其他天文台发现的FRB 121102爆发特性进行了比较。我们报告的前驱脉冲与主脉冲仅相隔17毫秒，这是迄今为止两个独立脉冲之间报告的最短间隔。我们还提供对该活动中所有FRB 121102检测到的数据的访问。
