My husband and I have just seen a line of about 15 lights moving in a straight line, quite high above the cloud level with a gap, and then 5 lights, a gap, another few, a gap, 1 light, a gap, and a few more.

They were moving at the same sort of speed as I would expect a plane to move at - almost like a train in the sky with a banner flying behind. They were in the sky for at least a minute.

I had seen a shooting star a few minutes before and it wasn’t one of them... what could it be?

Could it be Elon Musk’s satellites?

Given the date and timing, this could be most like the Starlink satellites in their "stacked" configuration. They are currently in a line, but they will later move to separate orbits. Dr Marco Langbroek has a video of a line of 60 satellites.

They won't stay in a line; they have ion engines that they will use to spread out into separate orbits.

    $\begingroup$ Wow. The manner in which they're moving across the sky is crazy. Direct link to the above video, for anyone wanting a quick look: vimeo.com/338361997 $\endgroup$ Commented May 25, 2019 at 7:06

    $\begingroup$ Normally air forces do that. Saw in with elicopters. Better I stop or I go political ;-) $\endgroup$

    $\begingroup$ More details and the video are also available on Marco Langbroek's SatTrack Leiden blog entry $\endgroup$ Commented May 25, 2019 at 17:00

    $\begingroup$ My computer doesn't like Vimeo. Here it is on YouTube. - Are they so bright because they're already using the ion engines? $\endgroup$

    $\begingroup$ Is there any information on how long they are going to stay “stacked”? The satellites supposedly passed over my location an hour ago, but I couldn't see anything due to overcast weather. $\endgroup$
