Today, an hour before sunrise, I noticed a bright, unusually structured cloud in the eastern morning sky (location: north of Hannover, Germany). I took photos between 6:40 CET (solar elevation -8°) and 6:55 CET (solar elevation -5.8°) while the cloud was slowly fading.

Apparently there was a rocket reentry last night, which was seen and filmed over Germany. Perhaps the cloud is its remnant?

"In the last couple of years, there have been roughly 500 re-entry events per year, and people are talking about 10,000 in the not-too-distant future. That’s about one an hour. So we’d like to understand the implications as soon as possible." (via @ScienceNews)
