Did anyone observe Noctilucent cloud (NLC) last night (25th/26th May)? I
note that it was (possibly) observed the previous night ....

http://www.nlcnet.co.uk/nlcreps.htm#may

Being up and about ~0100Z (2am BST) last night, and looking towards the
NNE/NE, there was a reasonably bright, silvery-white glow in the sky,
towards the horizon, roughly 10° elevation. Because there was so much
tropospheric cloud about, I initially discounted any mesospheric cloud,
but I have been in touch with someone else nearby this morning who also
wondered whether NLC was involved? Also, about that time, the
tropospheric cirrus shield was thinning/breaking temporarily.

Martin.

It looked nebulous last night Martin but nothing like the night before.
There was a lot of cirrus here and didn't report to nlcnet because of that.

I've sent you a couple of webcam shots by email.

.... thanks for those; should I report as 'possible' or would that be
skewing the data too much given the high degree of uncertainty? In our
location, the glow could have been due to urban lighting off low-level
clouds (that is our 'urbanised' direction).
