Very cool movie! Thanks for the story/link! <div class="Discussion_UserSignature"> </div>

Cool video docm. Do you know how long a time the video represents?<br /> <div class="Discussion_UserSignature"> </div>

 

[docm]

The SOT has an exposure rate of ~0.3 to 0.8 seconds per frame and this video is 503 frames. <br /><br />Not counting any delays between frames, which we have no info on either way, in duration so the raw duration could be 160-402 seconds.<br /><br />All you ever wanted to know about Hinode's imagers.... <div class="Discussion_UserSignature"> </div>

As soon as the mainstream recognizes that the sun is a conductor of electrical currents from space, then it's not quite as "mysterious" anymore. <br /><br />What wonderful and exciting new images!
