We use {\it Gaia} DR2 photometry and proper motions to search for the hypothetical tidal tails of the Galactic globular cluster E\,3. Using a modified version of a classical decontamination procedure, we are able to identify the presence of an extended structure emerging from the cluster up to $r \sim 1$\,deg from its center, thus suggesting that this poorly studied cluster is undergoing a tidal disruption process. These low surface-brightness structures are aligned with the direction to the Galactic center, as expected for a cluster close to its perigalacticon. Different scenarios to explain the important amount of mass lost by this cluster are discussed.

低质量球状星团E 3的破坏

我们使用 {\it Gaia} DR2 测光和自行搜索银河球状星团 E\,3 的假设潮汐尾。使用经典去污程序的修改版本，我们能够识别出从集群中出现的扩展结构的存在，该结构从其中心到 $r \sim 1$\,deg ，因此表明这个研究不足的集群正在经历一个潮汐破坏过程。这些低表面亮度结构与银河系中心的方向一致，正如预期的靠近其周缘的星团一样。讨论了解释该星团损失的重要质量的不同情况。
