Storm Edge finder
« on: March 16, 2011, 08:06:44 am »
I must have a go at this later! Not too sure many people will be able to take part as not everyone will be able to mark the storms that way - shame we can't have a little interface just for this task.

Ok, sorry, perhaps i emphasised the replicating what i did too much. What i first thought would happen is that everyone could go to movie clip from the link provided in the blog. then reply here with nothing more than a time that they think the storm disappears..

then if someone happened to find another storm, they could link it to a thread with a time they think it disappears. they do not need to do any of the fancy drawing, just tell me when you think it disappears.. then other people can try to see if they agree..

I included the fancy drawing as a way of explaining what i did.

Ah - much easier! Though I like the fancy drawings!

Ok.. this post and associated blog is having much less enthusiasm than the circular storm idea..
Did I pitch this little project at a level that is generally too difficult?

any feedback would be most welcome..

it will help me to try to think of something else..

thanks,
Neel

Hi Neel,

to be honest I'd have to read the blog post again (but Zooniverse Blogs isn't reachable at the moment). As far as I remember my impression was that the task was not all too difficult. But maybe the idea just didn't generate enough attention for everybody to remember while they're classifying. I at least must admit that I had forgotten about your little extra task.

I think bumping this thread (and maybe repeating the task description here as soon as the blogs get available again) and stickifying it (which I'll do right now) is enough. Once enough people have done their first "x" classifications I think they will keep this in mind (again I'm judging from my own experience which might not transfer to everyone else).

So here a call to everyone: Please read Neel's post once more and try a few classifications of that sort. Thanks for your efforts.

cheers

Ok, here an example for our tasks:

Consider this spot video. (20100417)

The part that is expected of us in this exercise is rather simple: I choose to describe the CME from about 19.70 to 25.

It was visible in both A and B.
In B the last frame where I think the shape if the CME is at least very vaguely is 23.50. From 23.60 on, at least the top of the CME shape fades to much to be reliably pointed at. What fades first is the top of the CME shape (at least that's my impression)
Pretty easy - eh?

So far for the necessary part. The fun (and time consuming) part that is not required for the exercise is taking (and possibly marking) a screenshot of the CME just prior to fading:



For the sake of completeness I'll also include the very first frame where the CME shape is not fully visible anymore:


This was just a short demonstration. For video A I'll continue the easy way. The last frame where the CME is fully visible seems to be 23.10. The part that becomes invisible first seems to be the lower right.

Ok , I hope this illustrates a bit of what we're asked to do (just tell when the storm starts fading too much and where it fades first) and what we could do additionally if we have the time.

cheers

CME from about 8.40 - 13.10 - SA

I think the full shape is till 11.40 before it fades away.

I keep forgetting about this mini project.

Here's an idea to make tracking these a bit easier, just quote the storm you want to add a measurement to, or pick another storm that you think can be measured like this and post it!

20090625 Starting at 7.30, A only
NSavani: A 12.90
Quialiss: A 12.60

20100417 Starting at 19.70, A & B
lpspieler: A 23.10   B 23.50
Quialiss: A 23.40    B 23.50

20100625 Starting at around 6, A & B
voyager1682002: 11.40
Quialiss: A 12.10, B 11.60

And a new one, Els posted this one in the circular storms thread
20080801 Starting at around 24.5, A only
Quialiss: 28.50

Hey lpspieler,
thats great thanks for letting me know that the task is not excessively difficult.
And congratulations for trying to tackle the image manipulation. It was well done. - yes it can be rather time consuming. If its any consolation- it is stuff that i often need to do myself for other research ideas.

But like i said, not really necessary. Just nice to visualise.

This is a great idea. If you can, please post your answers in the format above.
It will really help me collect all the information.

Just one thing, if the storm is new opposed to giving your opinion to another, please highlight/mention it as a new storm of interest.
This will help me to make a table the different storms, and help others to give their opinion.

Thanks

Adding to..
20070417 starting at around 9.40, A only
voyager1682002: A 13.50
Quialiss: A 13.60


A pretty triangular storm.  Wouldn't make the grade for a circular storm, but it does have a very defined shape.
20101017 starting around 4, A & B
Quialiss: A 6.70 B 6.60


There are actually a number of interesting storms in that clip, I wonder if they're interesting in terms of this project?  there's a storm starting 20 that simply doesn't have a back(but is otherwise well defined, at least on Ahead, until the front reaches the edge of the frame) and another at 35 that is massive and very well defined, but because of the size one side of the storm runs out of the FOV quite early... and another at 45.5 that has such a weird shape I was having trouble figuring out what I would call the 'bottom' that I decided to post the triangular storm from the beginning of the clip. 

... So, I guess the question is, what is an 'ideal' storm to make these measurements on?  The circular storms got me looking for simple shapes that are easy to trace, but I'd hate to make that assumption and have the weird twisty ones be more interesting for this project.  ;)

I'm having a hard task finding nice circular storms for this, but how about this one?
It's a lovely circle, but the base of it sneaks away out of shot as it grows.....
http://www.solarstormwatch.com/favourites/4565
or, if this link is right,

20101022 Starting at 16.60, A
Rookwings: 20.60

[I have my monitor's brightness right up to see better, in case that makes a difference?]

P.S., Yikes, I don't think the date number will work, sorry  ???
