Observing tips: Look west 30 to 60 minutes after sunset when the Sun has dipped 6^o to 16^o 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.

P-M Hedén, Vallentuna, Sweden Jun. 26, 2008	#1, #2, #3, more	At last some NLC here in Sweden too! Photo details: Sigma 20mm & Canon 450D
Stanislaw Rokita, Torun, Poland Jun. 26, 2008	#1, #2, #3, #4,	The evening was cloudy so I didn't expect nothing special on the sky, but when I looked about 11pm through my window I was really surprised: the northern horizon was very bright, but it wasn't "normal" light, that were NLC! I was shocked - they were so bright and perfectly visible. It was amazing. I didn't expect to see such view almost from the centre of the city. Photo details: Fuji FinePix 6500fd, ISO 100-400, Ap. 3-3.9, ex. 3-8s.
Aurimas Dirse, Vilnius, Lithuania. Jun. 26, 2008	#1, #2, #3, #4	Noctilucent clouds in Vilnius. It is a second night they are visible. But this night they were very bright and very high in the sky!
Michal Laszczynski, Gdynia, Poland Jun. 26, 2008	#1, #2, #3, #4	Very spectacular bright noctilucents show this night! Pictures were taken between 1h52m and 2h11m after sun set. Lower clouds finished this spectacle. Photo details: Canon A620, ISO 100, 1.3s to 6s for last shot.
Camilla Bacher Kiming, Greve, south of Copenhagen, Denmark. Jun. 24, 2008	#1, #2, #3, #4, more	I've been watching NLS' for more than 20 years, and this was one of the better displays. Very bright and with excellent detail. An interesting observation is that NLC's seem to be bright at first, then get weaker and with less detail, even if it gets darker. Wonder if sunlight plays a role in their formation?
Cezary Wierucki, Kolbudy, Poland Jun. 26, 2008	#1	The NLC that is currently visible is the brightest one I've ever seen so far. Photo details: Canon 400D, ISO100 4s exp via 17-40 f/4 lens set to 17mm

Northern Lights Photo Gallery: A solar wind stream hit Earth on May 20th causing a mild geomagnetic storm and Northern Lights around the Arctic Circle. The auroras of May 21st were so bright, they were visible in the twilight blue sky above Nunavik, Quebec.

"The sky is blue at 1 o'clock in the morning when I took these pictures," says photographer Sylvain Serre. "At our latitude at this time of year, it is blue all night long--and it's never a dark blue. So, at 1 o'clock in the morning, the sky is bright and I can see only a few stars."

In spite of this extra glare, Serre was able to see the auroras. "I saw them with my unaided eyes. The clouds made it difficult, but the clouds were moving slowly while the northern lights were moving faster." This, plus the green color of the auroras, made it possible to sort things out.
