Reports Report 2642z (Event 2642-2026)

Observer
Name Matthew K
Experience Level 1/5
Remarks Was incredibly fascinating, checked twitter immediately to see if anyone else saw it and I saw an account from Michigan and an account from Illinois stating they just saw a “shooting star” but nothing mentioning the white circular explosion I witnessed. Mesmerizing experience.
