Thanks, Katy! This was actually planned and for once actually worked out. The weather was clear on a night with a bright pass, and I could actually see it faintly well before the flare to let me line up the shot. Only the light pollution kept the before and after trails from showing up.

Wow this is AWESOME David! So amazing. Did you know you were going to get this? My one-and-only experience with iridium flare was pure accident, serendipity.

Not something I'll ever get to see in summer, here.

Thanks, Eileen. This one actually turned out almost how I wanted. If it wasn't for all the light pollution around me, I could crank up the ISO and open the aperture all the way like I did at a friends place out in the country and see a lot more of the before and after trails which are faint
