On our star, the Sun, the sunspots are seen in a belt around the equator, but now scientists have observed a large, distant star where sunspots are located near the poles.

Hill's NSO colleague Sushanta Tripathy also turned to helioseismology to investigate the recent solar minimum, finding that in acoustic oscillations deep within the sun there were in fact two separate minima — one in late 2007 that did not correspond to the sunspot minimum, and one around late 2008 that did.

High - resolution observations are presented based on direct imaging, two - dimensional spectropolarimetry with Fabry - Pérot interferometers, and scanning long - slit spectrographs to introduce some of the science cases for high - resolution solar physics: (1) statistical properties of flows in and around pores and sunspots, (2) chromospheric dynamics associated with newly emerging flux, and (3) flare diagnostics from near - infrared spectropolarimetry.

During around 90 % of the entire period between the start of the CRF count (1951) to now, the CRF has been higher than 3600 (x100) per hour [if one looks at the climax CRF / sunspot number plot on the page I urled and compares this with the data in the downloadable datasets on that page one can work out that a CRF count of 3600 (x100) per hour corresponds to around the 83 % level].

So, I just sit around and count spotless days (11 in a row most recently) and wait for the climate to do what it always does whenever the sunspot count is this low.

I understand that the Group sunspot number extends further back than the Wolf number, but given the striking disagreement between the 14C & Group numbers around 1780 (Fig. 1), would it be better to use the Wolf number?

While the group sunspot record indicates high solar activity during the last 60 years compared to the preceding 350 years, the Wolf sunspot record reached today's values for a short period around 1780 AD (with the exception of the very strong sunspot maximum around 1957 AD).

We're already expecting a low intensity solar cycle this time around (not referring to the «Russian Astronomer» prediction of longterm cooling, but to the solar observatories» predictions for the next 11 - year sunspot cycle just starting now).

In each rise and fall, the latitude of sunspot eruption starts around 30 ° and drifts to the equator, but the magnetic fields of the follower spots (sunspots usually come in pairs, called leader and follower) drift poleward and reverse the polar field.

It is far more related to the sort of measurements Livingston and Penn are making on the magnetic strength of sunspots, which has been decreasing steadily ever since measurements started around 1998.

Back in 2009, by analysing the data, I found that the global average sea surface temperature, the SST, stays fairly constant when the Sun is averaging around 40 sunspots per month.

And I predict a negative AO / NAO and El Nino bias through to around the next sunspot maximum, with California continuing a generally wetter phase until then.

The linear trend over the sunspot record from 1749 rises from around 40SSN (around my empirically determined ocean equilibrium value) to 63SSN just before the big crash in solar activity in 2004.

Yet according to this study: http://www.ucar.edu/news/releases/2006/brightness.shtml «Data collected from radiometers on U.S. and European spacecraft show that the Sun is about 0.07 percent brighter in years of peak sunspot activity, such as around 2000, than when spots are rare (as they are now, at the low end of the 11 - year solar cycle).

The variability reduced around the last sunspot maximum because of a brief positive NAO regime, and has started to increase again.

Sea ice loss accelerated from the mid 1990's because of a negative NAO regime (apart from around the last two sunspot maxima) driving a warm AMO.

Most solar flares and coronal mass ejections originate in magnetically active regions around visible sunspot groupings.

During the LIA and the Maunder minimum, sunspots «disappeared» around 1645.

Prior to direct telescopic measurements of sunspots, which commenced around 1610, knowledge of solar activity is inferred indirectly from the 14C and 10Be cosmogenic isotope record in tree rings and ice cores, respectively, which exhibit solar related cycles near 90, 200 and 2,300 years.

interesting that the decoupling of sunspots and had / crut takes place right around the same time that a large (and by large, i mean 30 - 40 %) number of ground stations were removed from the dataset... doesn't prove anything, but likely worth a look.

Here is the power spectrum of the daily sunspot number, you can see the triple peaks around 10.81 yr and the «long - term» peak on the long side of 100 years: http://www.leif.org/research/FFT-Daily-Sunspot-Number.png

Even the «regular» 11 and 22 year sunspot cycles vary in length by (from memory, it's late) around 10 - 15 % or so.

(Quick reminder: The delay of one sunspot cycle in the ND theory overcomes the objection that because TSI and so on peaked around 1986 and surface temperatures kept rising to about 1997, the Sun can not be driving temperature.

The delay also means that the fall off in bulk TSI around 2004 presages a fall in surface temperatures around about one sunspot later, around 2017: 2004 + 13 = 2017.

In theory it should follow its average 11.1 year solar cycle and increase and decrease the sunspot number as it goes through the cycle, which increases or decreases the solar forcing around.3 W / m2.

Including the new cycle resolves the problems mentioned above and leads to a consistent view of sunspot activity around the Dalton minimum.

It is harder to be certain there because all we have to go on is that sunspots tripled in that period from a relative lull around 1910.

(re) established in this blog we have: — there is an Atlantic oscillation, which might produce a 30 year long rising surface temperature trend — the sunspot number had some (positive) correlation with the climate in the past and is unusual high for the last 50 years — there might be uncertainties in the temperature measurements (UHI for example)-- specially for Tony: around 1880 it was cold most likely because of the sun!

It is built around the discovery in 1991 by the Danish atmospheric physicist Dr Eigil Friis - Christensen that recent temperature variations on earth are in «strikingly good agreement» with the length of the cycle of sunspots — the shorter they are, the higher the temperature (2).
