Time-lapse of AARTFAAC detections of radio meteors in Perseids 2020

LOFAR AARTFAAC images (integrated over all observing bands) during the Perseids meteor shower in the night 2020 August 12 --13. The large-scale diffuse emission is the Galactic plane. The brightest radio sources Cassiopeia~A and Cygnus~A have been subtracted, sometimes leaving some artefacts. In red, trajectories as computed from the CAMS BeNeLux optical observations are overlaid. Observing frequencies were in the range 30 to 60 MHz.本数据集包含2020年8月12日至13日夜英仙座流星雨期间，LOFAR AARTFAAC在所有观测波段下积分得到的图像。图像中的大范围弥散辐射即银河平面射电辐射。已扣除最明亮的射电源仙后座A（Cassiopeia A）与天鹅座A（Cygnus A），该扣除步骤有时会残留部分伪影。基于CAMS BeNeLux光学观测计算得到的流星轨迹以红色叠加于图像之上。本次观测的频率范围为30至60 MHz。
