question

What modulates our Sun? The majority of science work on the principle that the Sun is self modulating and each solar cycle is a product of a random number generator. There are others that suspect the Sun is modulated by the planets with a special emphasis on Uranus & Neptune. Thanks to Carl Smith who has recently left us we have new knowledge that significantly adds to Jose, Landscheidt & Charvàtovà's work.

MARCH NEWS

March finishing with a whimper as a single unipolar region counted today with overall area falling again. Returning region 1429 is dead in the water with a weak magnetic signature at this stage. March has been weak overall, but there may be some action in the pipeline.

A single region counted today with overall area falling slightly. The specks continue to dominate as the Sun continues its slumber. Some talk of the return of region 1429 returning with a CME on the far side recorded on the 26th March. Old region 1429 is now rotating onto the face in the north and at this stage is a basic plage, but there is more to follow.

A single region counted today with overall area gaining slightly. Even more specks today, if L&P are measuring today they would have a field day. Some possible future activity in both hemispheres showing on Stereo Behind.

A single region counted today with overall area remaining static. Region 1442 has not passed the 24 hour rule and will not be counted yesterday. Many specks this month which should place a large gap between the LSC and the big boys.

F10.7 flux remaining low. The southern hemisphere looking stronger than the north right now, although still very weak. Many other specks falling below the Wolf type threshold.

One small unipolar region counted today with overall area decreasing again. Region 1427 decaying rapidly and failing the 24 hour rule, and so will not be counted yesterday. Today we have one spot and about 14 specs at 03:00 UTC, if L&P were measuring today we would have a speck ratio of 14 to 1. L&P treat each speck with the same importance as the single spot, so the average reading today would show a very low level of magnetic strength skewed because of the high speck ratio. Specks have a much lower magnetic reading in general.

Four regions counted today with a new small region appearing, and overall area dropping a moderate amount again. Region 1428 not passing the threshold with other regions looking weak. Region 1429 may be amongst the largest regions of SC24 but we must keep in mind it is a reversed polarity region. Any flux traveling to the pole from this region will reduce the reversing process required for a Hale cycle reversal. The pipeline continues to look weak.
