I have never witnessed such a beautiful display of noctilucent clouds in my life. It was overwhelming. I began in the early evening with the typical volcanic sunset we have been seeing the last week but around 23.00h local time delicate tendrils began to reveal themselves , ten minutes later they became more visible and brighter until twenty minutes later an enormous display from West by Northwest to North by Northeast became visible, very high also. A bright passage of the ISS made it even more perfect ! Greetings, Bruno.
