Interesting piece of space junk illuminated by the sun. The “cross” and halo are artifacts of the camera CCD and lens.
On a brighter note, while metal detecting at the river tonight, just three hours ago I saw two awesome reentries of space junk steak across the sky. The first died in a large fireball, and a minute later another piece entered and evaporated in a streak of white, yellow, orange and green debris trail. They both were visible for at least two seconds. What a sight!
Green fire indicates copper, so it was probably electronics with wiring, most likely an old spy satellite....................
