Bei diesem Einschlag liegt die Peakfrequenz in der Rising Front und dem Event Peak unterhalb der Zentralfrequenz. Also bewegt sich der Brösel von der Linie Sender-Empfänger weg, oder?

In der Falling Front liegt sie aber darüber. Treibt da der Höhenwind die Ionisationswolke wieder auf diese Linie zu?

Dieser Brösel scheint zerbrochen zu sein, wie der Anstieg der Signalstärke im Peak nahelegt. Er hat sich mit 25 m/s auf die Linie Sender-Empfänger zubewegt.
