Solar Timelapse

[Peter Ward]

This is a short section of a much larger data-set that I had been working on for some time.

The animation loops, hence a small jump (partly due to the Sun's rotation) can be seen as it recycles to the start point during the sequence.

I actually didn't know the flare shown was occurring, as the data capture was unattended..a pity as an hour's more data would have given a better result.

Anyway the link is here (http://www.atscope.com.au/BRO/gallery310.html)

(a Quicktime browser plug-in is required.... the sequence actually plays better by saving the .mp4 and then loading it into a dedicated player)

That is incredibly clear. Looks like NASA took it!

Peter - that is truly spectacular!

[Peter Ward]

NASA? Not Another Solar Animation? :)

Thanks guys.

Fantastic, i didn't know you had SOHO in your backyard !

[iceman]

Damn that's good.

Wonderful work Peter !

Hi Peter,

That's amazing. How long was the timelapse?

Cheers,
Mark

Very cool animation. QT might not be ideal. Playback is sketchy. Tried VIMEO?

[Peter Ward]

Actually is an H264 codec. Vimeo is quite lossy...



About 4 hours







Thanks again guys.

By the way, the "big" version will debut at CWAS.

Amazing work. Its amazing how the surface is writhing around. Its hard to think with that the Sun is a blazing fusion. You'd think it would all burn up rapidly and not last as long as it does.

Solar images are all a bit static and alike but this is wonderful - It's ALIVE!

John.

[Bassnut]

wow, thats very impressive. Excellent!. Yes, ALIVE.

[Bassnut]

Not for me it wasnt, perfect.

[h0ughy]

nort a bad effort there Peter

[Peter Ward]

Thanks guys...I've discovered in the world of video there seems to be a million Codecs...some preserve data, others melt it, some play smoothly, some are just plain cr@p.

Then there are the computers on which the stream is viewed.... some cope very well, some choke better than Greg Norman at a US open.

Anyway I've uploaded a fairly high-res HD stream...so, depending on your system, you may, or may not have smoothly-flowing video.

Such is life :)

As for the nitty gritty..... each of the 200 odd video frames (ie just a few seconds of video) was generated from 200x 600 frame .avi's.

Yes that's about 120,000 frames that needed processing....Even with a Hex Core I-7 CPU it takes time....

Fantastic stuff Peter.

[Star Catcher]

Really classy stuff Peter!! :)

[Peter Ward]

Thanks Ted...appreciate the feeback



Glad you like it :)

[rustigsmed]

thats fantastic, can't wait to see the betterversion! (if you release it to the public of course) ;)

was the panning in the video 'real' or did you have the entire fov while recording? amazing stuff congratulations the hard work has paid off. :thumbsup:

Cheers

The actual field of view was quite a bit wider.....hence the post production Pan to better show the detail. One of the big challenges is how to manage thin cloud, seeing changes and the Etalon itself doing weird stuff over many hours...I've still much to learn.

[SkyViking]

Very impressive work there Peter, the animation is beautiful. It's really interesting to see the boiling surface in action like that! A lot of effort but definitely worth it :thumbsup:

[hickny]

Fantastic!!!!

[Peter Ward]

Thanks :)



I'll take that as high praise indeed from the wizard of ultra-deep imagery :)

[icytailmark]

wow fantastic peter.how many days of data was all of that?Do you image the sun with a 4k ccd camera?

[Peter Ward]

While the whole project ( which includes quite a bit more time lapse data) took many weeks, that short time lapse sequence was taken over around 4hours....camera details etc. are on the linked page ;)

[GOTO]

Wow, awesome work Peter. You should run workshops ;)
