My son and I were actually travelling north on the A1 between Tempsford and the Black Cat roundabout around 5.35pm on New years Eve 2017.
I have tried to report accurately the positions of the sighting from a standing position in Tempsford.
This was an absolute breathtaking phenomenon / experience that we both saw.
At 54 years old having travelled the world, all I can say is that I have never witnessed anything like it.
Absolutely mind blowing.
