Summer 2007

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 high latitudes such as Scandinavia and Canada, 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.

Photographer, Location	Images	Comments
Frank R. Larsen, The Lidemark Observatory, Koege, Denmark Jul. 10, 2007	#1, #2, #3, more	We were at the observatory, drift-aligning our new LX200 12", when it started. The Moon was up and Mars was rising in the East. Beautiful waves, the Moon and Mars and a few stars made an awesome view. Photo details: Canon EOS 350D, EFS 18-55mm. ISO 1600, 1-2sec exposures.
Koen Miskotte, Ermelo, the Netherlands Jul. 10, 2007	#1, more	Just before leaving to my work I noticed some noctilucent clouds outside. Photo details: Canon 10D, Canon EF 2.8/15 mm fish eye lens.
John C McConnell, Maghaberry Northern Ireland. Jul. 9, 2007	#1, #2	In thirty years of observing NLC's I have never seen such odd structures, it was beautiful! Photo details: Canon EOS 400D, ISO 400, 8 seconds.
Martin McKenna, Maghera, Co.Derry, N.Ireland Jul. 9, 2007	#1, #2, #3, more	Last night--all night long--we enjoyed a most beautiful NLC display. It is the best of the season so far. This display crossed the zenith reaching 120 degrees in height and passed the Moon and planet Mars. Rich colours and outstanding detail were present which changed from minute to minute which was difficult to describe. I seen whirls, elongated loops like the orbit of a comet, bands, shadows, herringbone etc. At one stage I seen the bones of a dinosaur with long skeletal tail which reminded me of Robert Leslie's descritpion of a 'great saurian embedded on a slab of stone'. Great show! Photo details: Fuji S5600 5.1MP, ISO200, 8 - 5 sec exp.
W McLean, North West River, Labrador, Canada Jul. 9, 2007	#1	These blue filigrees appeared in a deep blue sky right after dark, and persisted almost until local solar midnight. Our latitudes are not Midnight Sun, but at this time of year, there's Midnight Twilight, which was the original reason for the photographic excursion. The mosquitoes were miserable. Photo details: Nikon Coolpix 950, 1 second exposure, aperture not recorded (dots are CCD artifacts.)
Paul Evans, Larne, Northern Ireland Jul. 9, 2007	#1, #2, #3, #4, more	This excellent display began sometime before 0200 BST when I awoke to see a huge display in progress. Over the next hour and a half it grew in size but became more dispersed until it faded into the oncoming dawn. The best display I've seen so far this season. Photo details: Minolta Dynax 5D camera, 50mm lens
David Roles, Edmonton, Alberta, Canada Jul. 5, 2007	#1	One of the two best NLC displays I have seen this summer. Photo details: 200 ISO, 6 seconds f4, 24mm lens.
Keith C Heidorn, Valemount, British Columbia, Canada (52o 46' N, 119o 15' W) Jul. 6, 2007	#1, #2, more	On 6 July 2007, in the Village of Valemount, British Columbia, Canada (52o 46' N, 119o 15' W), I witnessed a display of noctilucent clouds. The following photographs were taken during the time period 10:59 pm (PDT) to 11:21 pm. Local sunset was at 9:22 pm. All but the last photo of the eight was taken without a tripod so the images are a bit blurry (I was afraid of missing the display). Photo details: Fujifilm FinePix S700 Camera, F3.5, exposure 3 seconds.
