I noticed these clouds stepping into my garden on the evening of the 15th June and having some energy still though I’d go out and see about getting one of my first photos of them. I headed out and made it along the road looking across a field to Cleadon with the clouds just above. This photo was taken at 0:22 with my Fuji X-E1 at 18mm, ISO 200 with a 7.5 second exposure.
The second photo was taken from South Shields looking North at a much wider field of view.
Noctilucent clouds are a phenomena in the upper atmosphere visible in twilight in latitudes between 50 and 70 degrees north or south in summer when the sun is below the horizon but the clouds are still in sunlight. This is possible since the clouds are actually around 50 miles above ground.
