Hi,

notilucent clouds visible earlier tonight around Ireland:

"This is the time of year to spot Nocti-Lucent Clouds (NLCs), which appear low in the N sky around local midnight, long after ordinary clouds cease to be illuminated by the Sun. They occur at a height of about 80km, and may be due to meteoric dust. They are a lovely silvery white in colour, sometimes with bluish tinges - a really lovely sight."

Cheers,
~Al
