Hi! If you think it might help, I'll be more than happy to give it a go!! G. Forgot to add... Tomorrow's the day. Would you like me to drop you a copy?? G. ` yes, as long as you don't cc me on the email... |

Looks like the Sun’s magnetic polar fields are turning the corner, and are on the way down.

A persistent state?Dr. Svalgaard has recently made available a presentation which he co-authored and presented in December 2009. It is: Hudson, H., L. Svalgaard, K. Shibasaki, and K. Tapping. “Microwave fluxes in the recent solar minimum.” Scientific, presented at the Hinode Science Meeting, Tokyo, 2009. www.leif.org/research/Solar-Microwaves-at-23-24-Minimum.pdf. Introduction
"The time series of solar microwave flux traditionally is divided into a flare component, a slowly-varying component, and a base level. Since 1947 there have been routine radiometric measurements, and the non-flare F10.7 index (2.8 GHz) from Penticton has had broad usage. Systematic radiometry at other microwave frequencies (1.0, 2.0, 3.75, 9.4 GHz) have come from Toyokawa and Nobeyama; these and other programs continue to the present time, thus including the five most recent solar maxima. We use the different measurements to show that the preceding maximum epoch (23) differed from the earlier ones. We also study the recent anomalous solar minimum and find that the joint variations of microwave flux, total solar irradiance (TSI), and sunspot number do not follow the patterns expected for TSI variability in maximum periods."
...
"Conclusions
• The change in F10.7/SSN seen in Cycle 23 suggests an unprecedented phenomenon
• The Livingston-Penn IR observations of umbral field intensity also suggest a secular change
• F10.7 shows interesting behavior in the Cycle 23/24 minimum that we don’t know the causes of
• The normal 4-component models of TSI can’t explain what we see in the Cycle 23/24 minimum."
( Note: The four components are Base, sunspots, plage, active network)
...
"Speculations
• There appears to be a general secular change in sunspot behavior
• F10.7, supported by the Japanese fixed-frequency observations, is consistent with this pattern
• Sunspots do not appear to form as expected
• The Cycle 23/24 anomalous minimum may be a part of a change in the state of solar activity"
Pooh's Notes: 1) I assume that "secular" is not used in a religious sense, but rather in its sense of extended duration: "3 a : occurring once in an age or a century b : existing or continuing through ages or centuries c : of or relating to a long term of indefinite duration <secular inflation>" www.merriam-webster.com/dictionary/SECULAR 2) Were this a statistical quality control situation (which it is not, due to insufficient samples), a break below a lower control limit would indicate a change in the process being controlled. Dr. Svalgaard and others have monitored an apparent lower limit of TSI over multiple solar cycles. Mankind can not control the sun's processes, but it should investigate the persistence and cause of these observations. We may need to adapt.

There was a sequence of short cycles (15-19) followed by the longer C20, than C21&22 followed by the longer C23. If system gets too far ahead of it self it is not odd to see it throttling down, in order to keep within ‘tollgate speed limit’. |

The distibutor and or plug wires are short and it's miss firing. ;D Maybe due to that 'tollgate' speed limiter. Oh man now we have to change the timing on the thing. Thanks to Pooh, for bringing the above to our attention. Good Job! |

I wonder if Bill Livingston and his associates have been able to get any data on 1040??

If they did not get time for 1040 lets hope they will catch the present two. I thought they were getting some time end of January?

I have done some comparison to the December spots from WSO magnetic maps, however this is only a rough estimate, I would say that B strength is fractionally higher , while umbra contrast on the optical records has also slightly increased, i.e. the contrast is recovering, so if this is any guidance the sunspots will not become invisible.
Looking forward to see data from L&P soon.
