I did think Starlink, but there were only 2, flashing, travelling West to East, then about 5 minutes later, 2 more but going North to South...
I have seen Starlink before and there were more of them and they were traveling faster than whatever this was and appeared to be bigger, and having an W/S pair and then a N/S pair also made me think it wasn't Starlink..
I looked on flight radar and there was nothing, so thought satellite, rather than I was being watched by the Russians or the CCP...
FWIW, it was just before 8pm last night, in Barrow upon Soar if there's a way to see what was floating about last night...
