So I was out imaging the Orion Nebula on the 15th of January this year. As I was checking the images after, I noticed a yellow streak on one of the pics. I've attached it so you can see. It was taken at 9:37 Sydney time. The image itself is crap because a gust of wind blew at the time. Using the Satellite Safari app, I checked to see if there were any satellites traveling through at the time, but nothing was even remotely close.
So the conclusion I've come to is that either it is a satellite that's not registered on the app (eg a classified spy satellite) or it's a shooting star.
Thoughts? (I'm bracing for the flood of UFO comments
)
