You left open the issue of your understanding of why there should be an EXACT mirror symmetry and that it is solely an artifact of the presentatation and the analysis and NOT a property of the Sun. Do you now understand that completely?

Yes. Thanks again.</description>

		<description>Jim Hughes (04:42:34) :
&lt;i&gt;So are you saying that it is not somewhat odd that both hemispheres almost look like mirror images&lt;/i&gt;

I assume that repeating what I said:
&quot;The similarity is simply because this is a GLOBAL inversion that assumes [and forces] the two hemispheres to be identical.&quot;

will not improve the understanding. So, I&#039;ll have to elaborate:
The method by which the data is obtained &lt;b&gt;forces&lt;/b&gt; the two hemispheres to be identical. In other words, the solution is given as a function of latitude without sign, i.e. with no distinction between North and South. This means the the data really only consists for the upper half of the diagram. The mirroring is done after the data has been obtained to &#039;aid&#039; [but apparently causes more confusion than elucidation] in understanding of the phenomenon. It is therefore not remarkable that the two halves appear identical. If they didn&#039;t that would signal an error in the program that drew the image. The algorithm should be:
0) for B from 0 to +90:
1) obtain value at latitude +B from helioseismology
2) set value at latitude -B = value at latitude +B
3) draw the two identical values at +B and at -B</description>

		<description>Leif, 

Maybe remarkable was the wrong adjective to use but let&#039;s push the differences aside within your community. And I&#039;m probably on your side here anyway.   

So are you saying that it is not somewhat odd that both hemispheres almost look like mirror images even though the surface on both do not throughout the solar cycle ? And I was really talking about the one at 4,000 which you could access in the article....&quot;more graphics&quot;.    

And if so, why ?</description>

		<description>Jim Hughes (19:00:44) :
&lt;i&gt;The mirror image like similarities between the jet stream in both hemispheres, especially at the higher latitudes, is remarkable.&lt;/i&gt;
It is not. the piece is just usual NASA PR-hype. We have not solved the problem, just moved it: namely to why has the flow slowed?

The similarity is simply because this is a GLOBAL inversion that assumes [and forces] the two hemispheres to be identical.</description>

&lt;i&gt;Nasif Nahle (09:33:50) :
Please, would you be so kind as to give me the formula for converting SORCE data to real data?
The SORCE data is the real data. It is the other data that is wrong [too high by ~4.4 W/m2], but for consistency with older data it is more convenient to ‘correct’ the SORCE data. As long as one knows that that is going one, there should be no confusion.&lt;/i&gt;

Clear enough... Thanks again, Leif. :)</description>

		<description>I hope I&#039;m not repeating this latest news from NASA&#039;s NSO (National Solar Observatory) issued this study about our sun&#039;s lack of spots. I wonder what Penn and Livingston make of this:

		<description>Jack Green (07:20:45) :
&lt;i&gt;Could it be that there is some kind of wobble or other long term explanation for this differential rotation of the Sun? Interesting and of course we don’t have enough data to figure this out yet.&lt;/i&gt;
The differential circulation is caused by several things, including the Coriolis force [the same process that creates the Trade Winds in the Earth&#039;s atmosphere. The magnetic field also modulates the differential rotation [makes it less]. But the true relationships are only now beginning to be investigated, now, when we are beginning to explore the interior of the Sun observing the results of Sunquakes.

		<description>@Dr. Leif Svalgaard... Leif, I&#039;m trying to calculate the mean TSI for 2008, but my ciphers don&#039;t coincide with the average that you calculated. I took the database from SORCE-TIM; however, SORCE&#039;s database shows very low magnitudes, as 1360.5 W/m^2. Please, would you be so kind as to give me the formula for converting SORCE data to real data? I thank you in advance for your kindness.</description>

		<description>I found it on Wikipedia and whoever edits that says the cycle is due to the differential rotation of the sun produces twisted magnetic fields in an eleven year cycle. Could it be that there is some kind of wobble or other long term explanation for this differential rotation of the Sun? Interesting and of course we don&#039;t have enough data to figure this out yet.</description>

		<description>Leif:  Could all of these Solar Cycles be related to a cyclic mass balance going on within the Sun? i.e. A solar tide if you will together with mass being destroyed and energy being created from this?</description>

That ’some’ is my good friend, the much vilified David Hathaway.

vilified ? ....Ouch.  I appreciate his updates.   



rbateman (00:56:15)

That effort, unfortunately, does not include the data I seek: White-Light Faculae.
But thanks for trying.


Sorry ,  I guess I should have mentioned that. It was also for others to look at for other information. As far as the cycle trends (peaks) during the last few, and what your looking at. It&#039;s been dropping since Cycle 21. The peak values of Cycles 22 &amp; 23 were somewhat in the same ballpark with each other but the consistency of Cycle 23 was not as strong as Cycle 22. Although the descending part held it&#039;s own.</description>

<p>That ’some’ is my good friend, the much vilified David Hathaway.</p>
<p>vilified ? &#8230;.Ouch.  I appreciate his updates.   </p>

<p>That effort, unfortunately, does not include the data I seek: White-Light Faculae.<br />
But thanks for trying.</p>
<p>Sorry ,  I guess I should have mentioned that. It was also for others to look at for other information. As far as the cycle trends (peaks) during the last few, and what your looking at. It&#8217;s been dropping since Cycle 21. The peak values of Cycles 22 &amp; 23 were somewhat in the same ballpark with each other but the consistency of Cycle 23 was not as strong as Cycle 22. Although the descending part held it&#8217;s own.</p>

		<description>David Archibald (18:47:36) : 
Could someone please point me to where I can get polar magnetic field strength data as per this graph: http://www.geocities.com/vukcevicu/PFdiv.gif .
Leif Svalgaard (19:31:19) : 
Vukcevic has a formula that will give you the polar field at any time thousands of years in the future or in the past, so you don’t need observations. ……..

Dr. Svalgaard
Thanks for publicly ‘endorsing’ Vukcevic polar fields formula, a cynic would add &quot;no such thing as bad publicity&quot;. 
Thousands of years?  Next 15-20 would be fine, but for the time being it is in good agreement with above findings of Drs Livingstone and Penn. For curious here it is:

If you are considering longer term than it should be combined with the Cycle anomalies formula:

Any chance I might be able to see a part of it?</description>

		<description>Leif Svalgaard (22:56:49) : C O R R E C T I O N
Richard (21:26:18) :
&lt;i&gt;Leif Svalgaard do you have the yearly raw aa index data? If so his claim can easily be checked. Thanks&lt;/i&gt;
at http://www.leif.org/research/AA-Yearly.xls
1st col. is the year, 2nd col. is the raw aa-mean, 3rd col. is my corrected aa. Basically aa+2.531 before 1957. Why? See: http://www.leif.org/research/2007JA012437.pdf page 15. The 2.9 nT correction becomes a 2.531 nT correction after the effect of the dipole tilt has been accounted for.</description>
