odd remarks on 10039

[jan lameer]

Hi

While waiting for "the big puff" to happen, here are some statistics that I found in

The Role of the Sun in climat Change
(it is a standard work by Hoyt and Schatten, 1997 Oxford Press, ISBN 0-19-509413-1, should be in most
University Dep. Astr. Libraries)

here it is:

page 236 appendix 2
about Sunspot Groups

Individual spots per group 7 - 11
Mean lifetime of groups 6 days
Maximum observed lifetime of a group 134 days
Area of a very large sunspot group 2,256 millionths of solar disk, or 2.6 billion square miles

It seems by these figures that our mammoth is still only a growing infant, I hope it has learned how to say puff and CME and X-flare in a correct way.

What interests me (the book doesn't answer this), is whether groups past solar max live longer and are larger. I think so.
Could it be that this group 10039 is stable in being unstable? And how large is it in comparison to the great 1947 or 1972 complex?
Furthermore, the book suggest a 154 days cycle of enhanced solar activity that might be caused by statistics. Does anyone see a rithm in the current activity compared to past X-ray activity of the sun during this cycle?
