Hey guys,

I need to get this out because it's weird and strange and I can't explain it.
Yesterday evening, my husband and I were at a birthday party which mainly took place outside. I had just gone into the house to get some bread when the people in the garden yelled for me to come back and have a look.
There was what looked like a constellation of stars, 30 or 40 or more, but it was moving. It was moving at a steady pace and going westwards, at approximately the same speed as the ISS. It was very high up, unlike a plane, and the lights weren't blinking.
For the rest of the night, we all kept staring into the sky because none of us had an explanation (or seen anything like it before), and we tried to come up with possibilites, but it was neither a satellite nor weather balloons or something like that, and some of the lights were so close together that it couldn't have been a formation of planes.
I'd very much like to know if any of you has seen something similar (yesterday around nine p.m. over Northern Germany or in general).
Thank you.
