I witnessed a group of 6 or 7 golden objects move across the sky & as I tracked them they came together as one and disappeared.

I was on my phone sitting down at the top of a hill after a walk & as I stood up, I looked up and witnessed a semi linear group of bronze/white objects move quickly across the sky. I stood up and I tracked them for a few seconds & as I did so they grouped up, became one & disappeared. The sighting lasted around 5 seconds. They were seemingly close & each about the size of the moon when it’s at its highest point. They were silent and moved very oddly. This is the only time I’ve seen anything like this.
