“Our all-sky night camera caught this unusual bright object pass overhead, Highway 395 Inyo county, heading west over the Sierra Nevada. It was too late at night to be a satellite (plus satellites don’t travel E to W) and too slow for a meteor, the entire passage lasted 80 seconds. An aircraft might be possible, but normally aircraft at night flying high are almost totally dark and invisible, this thing got near magnitude -6 at the high point, with multiple colors white, green, pink.
“Unlikely to be aircraft headlights, since it got brightest when it was nearly overhead, not when approaching, so would be looking right at the object’s side when brightest. This is a rural area with no nearby airports. Was indoors at the time, so can’t say if it made any sound or not. No loud sound.”
