A clear sky but very hazy and light. We were there from 9:30pm but it didn't get dark enough to see stars till well after 10. Rhys and I were there to try out the ODK for photography and had a try at M13, too early for nebulosity, then a little try at M66 to see if the supernova could be seen, but the trees got it first. The only things of note were that it got cold and my camera and its box were knocked off the cupboards twice, by the dome moving. Once would have been enough but I didn't learn.
We saw what we thought could have been Noctilucent clouds. Certainly could have been but they were faint and faded soon after.
We closed down and left at 1:00am-ish.
