possible iridium pass or what?

Would it have been a low flying airliner on approach with its headlights on full beam? When there was work going on on the main runway at Dublin Airport there was another runway being used at night and the approach vector was right over Bray Head and Bray. Airliners every 2 or 3 minutes some nights. Boy did they have powerful headlights even at dusk.

Man, I hope not:laugh:
seriously though, I don't think so, it was full daytime and this thing was brilliantly bright, bright enough that it grabbed my attention while not looking at the sky, no contrail and sign of any kind of plane. If it was a light that bright I'd suspect you would see the plane also.

That'll learn me not to read the OP properly

Could it have been the Sun glinting off the underside of an aircraft. That could explain how it looked like two objects maybe catching both wingtips? Just a thought.

It could have been, it could have been anything, one thing is for sure is that it looks like no one else saw it, a real pity the sky wasn't better so I could get a long good stare at it.
