Ripples around the Sun (APOD 6 Feb 2007)

[Malde]

Hello,

I'm new to this forum, but have been using APOD since 1998. On today's picture (Sun Storm: Mass Coronal Ejection, 6th Feb 2007) there are ripples close to the Sun's surface. What are these due to...or are they just imaging artefacts?

I saw them and thought the same thing too. Having never seen such ripples before I'm inclined to think "artifacts" myself.

Hello Malde and welcome. I think mostly the ripples are caused by the storms on the sun. Like wind makes ripples on the sea.

I was wondering what happens to the ejecta as it is blown out into space! Does this cool down into debris and become meteors; or does it just become part of the solar wind?

If you are refering to the ring style ripples at the solar limb, I would think that they might be layering in the solar photosphere (atmosphere)??? They do resemble the shell style layering of the Cats Eye Nebula seen here http://us.st11.yimg.com/us.st.yimg.com/ ... 2_37523625
as well as other nebula caused near the end of the stellar lifecycle

If the ripples are real - what's the physics behind them? Governed by electrical and or magnetic fields?

[BMAONE23]

I don't know if the ripples are real or not. They might be created to fill in the area between the two images that were used to create this one composit image.

THe image formed has to be explained by the functioning of the sun and what drives it.

The answer lies in the inner core. Just like earth and it magnetic field the sun also has the same magnetic field.

The symmetry of the storm gives us the answer.
The question and asnswer is this.

What ever the core is made from it is pulsating creating this symmetry.

For the next few years I will be looking at the workings of the inner core, a key factor in the driving force of the sun and the cycles we observe that influence our weather on earth.

The image used for the APOD and an accompanying caption in the SOHO website are brought up when clicking on the "above image" and "this dramatic image" links in the APOD explanation. The caption is however very confusing, unless I'm missing something! Does anybody know the correct date when the image was taken. The caption currently reads:-

Blasting CME -- This LASCO C2 image, taken 8 January 2002, shows a widely spreading coronal mass ejection (CME) shooting billi Joseph B. Gurman Normal Joseph B. Gurman 2 2003-01-03T14:46:00Z 2003-01-03T14:46:00Z 1 NASA GSGC 1 1 9.2511 800x600 0 0 CME blast -- This dramatic coronal mass ejection was captured 7 August 2002 as it blasted billions of tons of particles millions of miles per hour out into space. The image was taken by the LASCO C2 instrument, which blocks out the Sun with an occulting disk so that we can see the fine details of the faint corona. An EIT 284Å image of the Sun itself, taken at about the same time, was enlarged and superimposed on the occulting disk.

I assume that information from at least two SOHO sources has got mixed up when producing the caption!
