Observing
tips: Look
west 30 to 60 minutes after sunset when
the Sun has dipped 6o to 16o below the horizon.
If you see luminous blue-white tendrils spreading across the sky,
you've probably spotted a noctilucent
cloud. Although
noctilucent clouds appear most often at arctic latitudes, they have
been sighted in recent years
as far south as Colorado, Utah and Virginia. NLCs are seasonal,
appearing most often in late spring and summer. In the northern
hemisphere, the best time to look would be between mid-May and the
end of August. See also 2003,

The first noctilucents I've seen this year. Really bright. Took these beautiful wispy clouds, one from the roof, a bit tricky with the tripod but worth it and one from the ground. Two stars visible.

Noctilucent clouds over Sigulda. Nikon D90, f/8, 1,6 sek. exp, ISO-400.
With begining of the summer NLC clouds shine bright blue-green light and flow like water in the sky.

Flying from Frankfurt to Helsinki, the first sign of NLCs appeared north of Berlin. Crossing the island of Bornholm and later Visby, they expanded to a massive complex with spectacular details. By the time we arrived over Finland, the clouds had spread to the zenith and beyond, spanning from southwest over north to the east.

Last night the NLC display was impressive in Stockholm, Sweden.
The clouds stretched far beyond zenith which is quite rare.
I took 14 overlaping pictures that make up this panorama of more than 180°.
