Here is a movie showing the luminosity and color evolution of SN2011dh/PTF11eon in M51 during June and July 2011. I recommend watching it in fullscreen and HD. Submitted by BJ Fulton (affiliation: LCOGT).

A time lapse from a week high in the Alps, in a spartan mountain hut, for observing the stars with many telescopes. Best viewed full screen and 1080p.

Hi all universe lovers!
We've posted a short HD film on the mysterious pulsating aurora at http://vimeo.com/28383882 , part of the series "Short stories of the Sky".
The NASA Themis mission has recently revealed that the underlying mechanism that causes pulsating aurora might be chorus waves, but there are still a lot of questions unsolved.
And while you watch the film, you might also want to have a look at http://www.vimeo.com/27315234 which shows the northern lights of 6 april 2000 as recorded on cinema film from the island of Terschelling in the Netherlands.

We hereby grant permission to use both films and stills of them on APOD and APOD only.

These should be the embedded aurora films

Pulsating Aurora:


geomagnetic storm of 6 april 2000

I like that Pulsating Aurora one. The timing seems nice. It's just a bit faster than real time, right?

Yes geckzilla, the footage is faster than real time, due to the necessity to use long exposures.

But the "speed of movement" of the northern lights is usually a combination of slow movements and fast movements combined.
In the editing we've tried to combine images that give an impression of what pulsating aurora looks like to the naked eye.

Pulsating aurora to the naked eye usually has slow pulsations of twice per minute, combined with faster pulsations of a few times per ten seconds. And sometimes there are rapid flashes too, almost like lightning ...

With a warm pair of coveralls and good gloves it's very nice to lay back in the snow for an hour and watch all the different aspects of pulsating aurora

Here is some recent timelaplse taken in and around South florida and the Everglades.

Another auroras video (with clouds). You can watch it in HD and full screen:

This is a meteor recorded just after a firework session. The image at the end is processed with all the video frames of the meteor and a long exposure photo. Better in HD and full screen.

It was taken at Yellowknife, Canada.
Feb. 2011.

As the aurora became more activity, it moves to the south.
Because the Aurora oval became bigger circle.

Hi all universe lovers!

We've put another Short stories of the Sky online: Dark side of the Moon.
It is about the earthshine or ashen glow effect that makes that you can sometimes see the rest of the moon when the moon is a small crescent.
You can find it at http://vimeo.com/29842888
enjoy!

Here is a video I made of last night's Aurora in Wisconsin

Hi, I made this video, hope you like it Thanks
