I agree.
iridium flash
I’ve seen it myself. You get a brief sun reflection off the solar panels of one of the Iridiam satellites. It happens a few hours after sunset. It was very disturbing to me until I found out what it was.
And if you are right on axis it’s 50 times brighter than Venus!
I saw an iridium flash in daylight. You can see them just about anytime if you are in that perfect location and time period.
