Ha, thanks for letting me know. I didn’t know satellites can create flares like this.
As all the other satellites were so dim I assumed it had to be something different.
For editing I chose the single sub with the flare and screen blended it in photoshop.
The old Iridium sats were cool because they could get to -9 magnitude for a few seconds if you were in just the right spot. You can also have some satellites that flare every few seconds if they're tumbling and keep hitting the sun at the right angle throughout the pass.
