Arcturus-

Based on the timings and path, I'm still wondering if it was Starlink-31714. What's 'LBM?'

Stellarium has BlueWalker 3 as below the horizon at that time.

I'm in Leicestershire.

I know the sheer number and rate of increase is a bit concerning.

Looking on Stellarium (assuming it's accurate), NOAA 18 appears too low. Starlink-31695 or Starlink-31714, seem to match the positioning more, however Starlinks usually appear white. Plus Starlinks seem to get in the way of everything.

Below is a screenshot from https://spaceweather.com/:

I saw what looked like a blue satellite going over the UK at around 23:18 -23:22 UTC (00:18-00:22 BST) tonight it went from west to east. It did not seem to look like aircraft navigation lights, because it didn't look like it was flashing, and it was a lot more blue than green. It also moved a lot like a satellite, straight and arching path/trajectory. Here's a photo I took at 23:20 UTC: With a Nikon D7100 (DX (APS-C) format DSLR) with a 50mm lens with the settings being: 8 sec, f/2, ISO: 800, +5EV. I haven't edited the photo this is the off camera jpg. Same settings clearly showing Lyra at 23:21 UTC: I think I might have seen it on Friday night (into Saturday) when the aurora was visible. I have seen slight hues on satellites before like Envisat looked slightly orange, but still I've never seen such a deep colour before.

Trackers are indicating there might be auroras right now. https://aurorawatch.lancs.ac.uk/: https://veryweather.co.uk/auroraTracker20.html:

So glad to finally see auroras:

Thanks for sharing @HnrKS. Hopefully the intensity will pick up again, especially as hasn't only the first of the six CMEs reached earth so far...

I really do hope I see it tonight. I think the aurora is the astronomical related thing that I've tried to observe the most without actually seeing it yet. And there's been a few times which I seemingly missed it by minutes.
