Screenshot of social media post. Reads, "Everyone was saying that the May geomag activity had no impact on the satellites. Of course we knew this was wrong. Over one hundred sats re-entered during this period and now a paper is showing that thousands of Starlinks had to move. Holy fuck. Imagine if those thousands had to re-enter. This. Is. Insane. We. Must. Stop. Launching. Shit. NOW. https://spaceweather.com"

I have no photos or videos, but I was on Topsail Island on vacation on June 4th around 11pm, where I saw a decently bright moving object erupt with a huge v-shaped tail for atleast 30 seconds. The tail was a faint green color. It fell from the eastern sky into the northeastern sky.

Google has been particularly unhelpful. Was wondering if you fine folks had any idea. I'm assuming space debris. But I cant find any other reports of anyone seeing it.

The Simons Observatory, a group of microwave telescopes in the high desert of Chile, is starting to gather data to attempt to prove or disprove the theory of inflation.

Scientists use the LOFAR telescope to observe low-frequency radio waves from satellites in large constellations for the first time. “Unintended electromagnetic radiation” emanating from onboard electronics in Starlink satellites was detected which could impact astronomical research. Further study is now ongoing.
