Acquisition details



Hello Friends,

this time a new animation of today's Prom. This time it is 50 frames in an interval of 180s. Also I have tried some new processing techniques. E.g. the automatic blackening of the sun disk during capture in FireCapture.

Some frames are blurry due to high clouds, but I have decided to keep them, because otherwise the animation would jump - and this is even worse.

Interesting in this animation is to see, that some plasma streams do or seam to revert their flow direction. First I thought i have messed up the frame sequence and triple checked it, but it is really reversing.
Others are an optical phenomena since the clouds rotate around an upright axis - like an tornado. So when the rotate on the backside compared to the front side it looks like they are suddenly reversing.

Some are also floating back and forth. Like waves.

There are many dynamic effects to discover.

Please enjoy!
