We present the results of MASTER Global Robotic Net optical observations of the region within the LIGO/Virgo S200219ac error-box, triggered during the O3 run. We observed 1124 square degrees inside the 3σ error box during a half month. We present the identified optical transients found during this study, which are not related to gravitational waves, and briefly discuss the MASTER observation strategy.

MASTER在观测LIGO/VIRGO S200219ac引力波事件中发现的光瞬变

我们展示了在 O3 运行期间触发的 LIGO/Virgo S200219ac 错误框内区域的 MASTER Global Robotic Net 光学观测结果。我们在半个月内观察到 3 σ误差框内的 1124 平方度。我们介绍了本研究中发现的与引力波无关的已识别光学瞬变，并简要讨论了 MASTER 观测策略。
