About the only significant even in the last month is that
the solar polar fields have begun their reversal, indicating we are at «solar max», which seems like a misnomer given the low activity observed at the moment.
The solar polar field [and its reversals] has a signature in the geomagnetic field that be followed back a century.

The new research, published today in the journal Geophysical Research Letters, explains that this atmospheric loss is driven by a
polar wind powered by an interaction between sunlight, the
solar magnetic
field and the molecules present in the upper atmosphere.
The team analysed data gathered over seven years by the international Cassini probe, and found that the interactions between Titan's atmosphere, and the
solar magnetic
field and radiation, create a wind of hydrocarbons and nitriles being blown away from its
polar regions into space.
By several measures — geomagnetic activity, weakness of
polar magnetic
fields, flagging
solar deflection of galactic cosmic rays — the minimum was the deepest on record, Hathaway said, although some of those records contain just a few cycles.
POLENET data is enabling new studies of the inner earth, tectonic plates, the earth's magnetic
field, climate and weather, and the
solar wind, and will lead to as yet unimagined discoveries about the critical
polar regions of our planet.
My question is this: the
solar polar magnetic
field strength is highest during minima of / between stronger
solar cycles?
Because I was thinking that in the eastward and westward drift of the magnetic equator, might be some other drifts and a relaxing of
polar fields with a trickle down effect during times of lower
solar wind dynamic pressures.
The second discrepancy occurring during the maximum of
solar cycle 24 can be explained in terms of the unusually extended
polar field reversal, with both northern and southern
polar fields being simultaneously positive for over a year, leading to a higher flux of GCR particles at Earth.
More precisely, the maximum of
solar cycle 24 was characterised by a rather slow and intermittent reversal of the
polar field, with north - south asymmetry, meaning that the Northern
polar field reversed on November 2012 and the Southern on March 2014, with both
polar fields being simultaneously positive for more than a year (Sun et al. 2015).
At the same time — research is showing a
solar UV / ozone chemistry influence in modulating atmospheric flows and
polar pressure
fields.
Hale suggested that the sunspot cycle period is 22 years, covering two
polar reversals of the
solar magnetic dipole
field... The start of the 22 - year cycle begins... This process of sunspot formation and migration continues until the
solar dipole
field reverses (after about 11 years).
I predicted that the
solar large scale
polar field will drop to levels not believed possible, for the following reasons:
As we approach the 2019 - 2020
solar minimum the
polar field method appears to confirm that SC25 will again be a below average
solar cycle.
The changes in the
solar magnetic
field impacting the Earth at
polar regions cause changes in surface pressure.
don't bother too much on SSN, rather look at the
solar polar magnetic
field strengths.
Just so you don't get confused with using the right terminology: When sunspots are high, the
solar polar magnetic
field strengths are low.
Like yourself, I also discovered a relationship between the position of Uranus and Saturn, shown here: I am just not sure yet if the correlation is caused by the position of the planets [gravitationally] forcing a change in the sun's
solar polar magnetic
fields or if it is just the other way around.
In terms of climate it means that the energy coming into the earth - system is not only the
solar radiation that «everyone» quotes, but also via light itself in the magnetic
field, as well as via the
polar Birkeland currents, and much like the stellar circuit proposed by Alven as reported in Parker, E. N., 2000, Physics Today, June issue p. 28, where the earth replaces the stellar object and the currents dropped down in density to dark current mode.
Their influence on the atmospheric circulation is focused on the
polar regions by the Earth's magnetic
field [the opposite phase of the changes in the Arctic and the Antarctic can be explained by the phenomenon of «
solar system dissymmetry» as a result of which fluctuations of
solar constant occur].
