The sky at Winfly

18 Sep

I know I keep harping on the beauty of this place, but wait…THERE’S MORE!

Another one of the unique opportunities of coming down during Winfly (mid August through September) is seeing the amazing things in the sky.  There are auroras, nacreous clouds, and the slow transition from darkness to daylight.  All of this makes looking at the sky a common occurance at any time of the day down here.

The following are views that I have seen down here that continually inspire me:

It's so amazing and looks so fake, but it's ALL REAL!

Yes, another spectacular view; nacreous clouds and the sunset make for good poems and lasting memories.

Auroras seen on 9.14.10.

Sunset from my room on 9.12.10.

I know it’s tough to get the full view of what I see down here, but these photos are a small attempt of the beauty I get the privilage to witness. 

Here is more information on aurora’s from http://www.atoptics.co.uk/highsky/auror1.htm:

The aurora or ‘Northern lights’ is one of Nature’s greatest spectacles. A display might start as a few upward shafts of light almost imperceptible against a darkening twilight sky. The shafts then take form, they brighten into greens topped with reds, they join to make wide curtains, move and flicker, they disappear then quickly return again. The silence as they change is somehow more eerie than the lights themselves. Sometimes the display is confined to the north, in others reds and orange cover the whole sky.

Aurorae are best seen for 2-3 hours around midnight although they can be visible from dusk to dawn. A moonless night well away from light pollution is ideal. They are most frequent and at their finest at high latitudes. Aurorae are concentrated in two giant ovals around* Earth’s magnetic poles.

Here is more information on nacreous clouds from http://www.atoptics.co.uk/highsky/nacr1.htm:

Nacreous clouds, sometimes called mother-of-pearl clouds, are rare but once seen are never forgotten. They are mostly visible within two hours after sunset or before dawn when they blaze unbelievably bright with vivid and slowly shifting iridescent colours. They are filmy sheets slowly curling and uncurling, stretching and contracting in the semi-dark sky. Compared with dark scudding low altitude clouds that might be present, nacreous clouds stand majestically in almost the same place – an indicator of their great height.

They need the very frigid regions of the lower stratosphere some 15 – 25 km (9 -16 mile) high and well above tropospheric clouds. They are so bright after sunset and before dawn because at those heights they are still sunlit.

They are seen mostly during winter at high latitudes.

Nacreous clouds far outshine and have much more vivid colours than ordinary iridescent clouds which are very much poor relations and seen frequently all over the world.
