摘要
我们报告了对既知瞬变现象的偶然观测，使用欧几里亚Q1数据发布。通过与瞬变名称服务器（TNS）交叉匹配，我们识别出164个与数据发布相吻合的瞬变现象。虽然欧几里亚Q1发布仅包含单时段数据，但我们能够对这些161个瞬变现象的地点进行欧几里亚光度测量。欧几里亚在, , , 和 波段对这些瞬变现象的光度进行深入测量或给出上限，这些测量涵盖了瞬变光度曲线的不同阶段，包括地面临时 survey观测的前后阶段。约70%的在欧几里亚观测日期前六个月内发现的、亮度超过24号的已知瞬变现象在欧几里亚图像中被检测到。我们的观测包括一例在峰值前15天即被欧几里亚近红外探测到的II型超新星（SN 2024pvw），以及对神秘核心崩塌超新星SN 2023aew的后期阶段（435.9天后峰值）观测。欧几里亚深光度测量为这些瞬变现象的本质提供了宝贵信息，包括其前体系统和能量来源，后期观测是其独特的贡献。此外，欧几里亚能够检测到一些先前被归类为无宿主星系的瞬变现象的宿主星系。Q1数据即使仅有单时段观测可用，便展示了欧几里亚数据的强大能量，这将应用于欧几里亚宽广调查中更大范围的天空。
