NOCTILUCENT CLOUDS GO WILD: An intense display of noctilucent clouds (NLCs) lit up the skies of Europe and North America last night. Bright electric-blue tendrils were visible through fireworks during Bastille Day celebrations in France, while the clouds descended as far south as Nebraska in the USA. Sky watchers should be alert for a repeat performance tonight. Observing tips and photos of the July 14th-15th display may be found at these URLs:
