NOCTI-LUCENTITY

For our friend that captures such great pictures of the skies;

AZIMUTH
Though it be night
there are still clouds at work
moving in the Dark
Silvery Linings at play softly
Shimmering high and brightly
Even as we sleep
Beyond the usual horizon
Hold your lense High
And keep your chin up.






Explanation: Alluring noctilucent or night-shining clouds lie near the edge of space, some 80 kilometers above Earth's surface. Of course, when viewed from space the clouds are more properly called polar mesospheric clouds (PMCs) -- seen here for the first time in image data from the Aeronomy of Ice in the Mesosphere (AIM) satellite. The clouds form over the poles in the corresponding summer season and are now being seen more frequently at lower latitudes. This paticular view from June 11 details the PMC structures forming over the north polar region in white and blue. (Black indicates no cloud data was available.) The AIM satellite should be able to track two complete cloud seasons over both poles to investigate possible connections between the high altitude night-shining clouds and global change in the lower atmosphere.

The preceeding was pulled from my 'Astronomy Photo of the Day" site, and if you click on the links, there are probaly better pics than the ones I have chosen and more info on NLC's.

They hover on the edge of space. Thin, wispy clouds, glowing electric blue. Some scientists think they're seeded by space dust. Others suspect they're a telltale sign of global warming.
They're called noctilucent or "night-shining" clouds (NLCs). And whatever causes them, they're lovely.
They are a faily recent phnomemna, first noted in 1885 after Krakatoa erupted.
I saw these and thought of Annelisa.

One more, shall we?

The fact it was reported after Krakatoa lends credence to the dust explanation.
In 1885, the Moon appeared blue for a week, hence the expression 'Once in a blue moon.'

Hey, Congrats on the award, Steve!

Special clouds for a special babe.

Fascinating post! I once saw a night-rainbow created by the bright light of a full moon after a rain. It was fainter than its diurnal cousin, but you could see the colors, nonetheless.

Aw....Steve. I know it doesn't take much to make my eyes water lately, but this was sooo special!
