Our cover picture ...
…shows a fireball on 1 July 2019 at 00:42 UTC (02:42 CEST). The images come from the two AllSky6 cameras in Ketzür (AMS16, Sirko Molau) and Lindenberg (AMS22, André Knöfel). The section of the satellite image shows that the observing conditions for both stations were relatively unfavorable, as high cirrus clouds prevailed. Nevertheless, both stations succeeded in recording it simultaneously. A striking feature is a flare in the middle of the trail, which partly illuminated the cirrus and therefore looks very extended. The corresponding video from Lindenberg, which illustrates this once more, can be seen on YouTube:
