Anyone else notice the weird triangular lights over Phoenix last Tuesday around 10pm?

Bit of a different angle on this but does anyone know if there were any reported sightings like this over the UK around the same time? I'm in Essex and last Tuesday night I was out in the garden about half ten and noticed something odd in the sky but I couldn't tell if it was lights or just one object. I'm rubbish at estimating distances and heights so I didn't want to post about it without checking if anyone else saw something similar first. My wife thinks I imagined it but I know what I saw was not a plane or helicopter, the movement was all wrong. Is there any kind of database where you can cross-reference sightings from the same night across different countries? Would love to know if whatever was over Phoenix might have been part of something bigger going on that night.
