Two very different ones, one small, one large. 


20090701 starting at 39.70, A only (There is a data gap at the start, but the shape persists so long that I think it's still interesting)
Quialiss: 42.70


20070625 starting at 51, A only
Quialiss: 54.30

20081225

Starting at 9.40

Looking at the video, might the events at 9.40-9.80 be the same storm?

What is it with pretty storms and data glitches?  This one has a spacecraft roll at the start and some mixed up frames with the coronographs at the end.. but looking at a different source these appear to have been fixed in later calibration passes, and the point where the front of the storm fades is visible, so here it is!  That, and it might even fit Neel's exacting criteria for 'circular' which makes it doubly interesting.

Haha! I found a square one!  :D
20101101 Starting at 12.10
A
Rookwings: 14.50
B
Rookwings: 14.40

There are two clumps with lots of other things in this video, I have no idea where one bit ends and another starts, so I threw my hands up and ran away screaming! They include a triangular one full-on at 40.70 and a "Sooty" glove puppet at 49.30.
Would anyone else like to take them on, please? I'm not even sure they're "interesting" enough.  :-\

[Edit] I found something else.
I can see from Quia's video Index that ElisabethB and lolinda put the 17.40 CME in the circular storms, but a bit later on, there's a trumpet formation which could be circular with a very wispy front at 40.10:

20100617 Starting at 36.80

I like your descriptions.  :D  They are very cool looking storms, but like you said, there's no structure to them to mark the boundaries of.  I've been stretching my brain around this paper for the past few days, here's a few relevant bits... "The typical morphology for normal CMEs is the so-called three-part structure, i.e., a bright frontal loop, which is immediately followed by a dark cavity with an embedded bright core"  The 'bright frontal loop' is the object of interest in our growing collection here, the sooty glove puppet and triangle both seem to be lacking it(and a cavity for that matter, but how do you have a dark area behind something that isn't there?) which isn't all that unusual... "The three-part structure is considered to be the standard morphology for CMEs, although observations indicate that only ∼ 30% of CME events possess all the three parts." Which says something about the wonderfully crazy complexity of CMEs that the 'best/standard' model accounts for only a third of the observed storms.

That's a beautiful storm that definitely belongs here, and I welcome you to the club of people who have posted duplicate storms to this topic! Don't worry, you're in good company.  Currently we're the only two members! The Spot videos overlap significantly, so that the last half of a video is the first half of the next one.  If you look back at the videos from 2007 the science team's decision to have so much overlap makes a bit more sense.. there was nothing going on!  So if there WAS a storm, you didn't want to screw up the measurements if it happened to fall between videos.

At first I wanted to pick the earlier one, but then I thought I should take the frame that is before the fading which is at about 26.50. I think there are two loops and somehow they are linked  ??? I am quite confused with this one ;D

The 'bottom' of this one is the first to go, the rest of the storm is quite persistent.

20080909 Starting at 16.5 A only
Quialiss: 21.50

Small storm but very clear

20081009 Starting around 47, B only
Quialiss: 52.5

BTW, I think we've picked out every storm that's suited to this study in 2007-2008... There's a few marginal ones I haven't posted (20080701 @ 26.5, 20080609 @ 13.60, 20081125 @ @ 26.0) because I'm not sure they are 'good' enough.

Not sure whether this qualifies as circular so I'm posting it here:

HI1B

20100615

ca. 22.00-24.90

The front seems to fade first, at 24.50
