Having just seen a beautiful & longer lasting trailing shooting star 90 degrees to the left a few minutes before my partner & I were utterly astonished to see such a bright & beautiful ‘bolide’ I believe that they are called. This was even more extraordinary than seeing a circumzenithal arc over a decade ago. I just wish I’d photographed it. N.B. The times of appearance could have been plus or minus ten mins or so from 11pm as I didn’t think to check my clock.
