Hi, die Geminiden waren in Anzahl und Intensität denen von 2017 sehr ähnlich. Ich werde noch bis zum 17.12.2019 weiterbeobachten. Am Abend des 16.12.19 erhoffe ich mir ein kleines Nebenmaximum an hellen Sternschnuppen, so war es zumindest 2016, 2017 und 2018. Interested to hear, did you have a know...
