FYI I struggled to use your first trajectory tool, but this is not the first time I have seen very bright objects at a similar angle. At the same time an aircraft was flying over so could be something from that. Very bright light approx 45/60 degree angle from the horizon looking to the south with a greenish tinge to the fore.
Previously about a year ago ish at the same trajectory but bright light with a more orange hue. My next door but one neighbour also saw as she was in the garden and I heard her gasp too.
It’s very odd but a few years back I lived in Westmarsh CT3 2LW and there was also a very bright light same trajectory(possibly a bit higher 55-60 degrees) with orange tail and a thud as it hit farmland behind my old house.
So sorry I did not know about this sight to report to you.
I hope this is of interest?
Please contact me I can be of any further assistance.
