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.

Three sunspot regions are recorded with the overall area increasing. The LSC is once again up to date.

The Laymans data was almost lost but 12 hours later (after disappearing) to their credit the all important laymans spreadsheet returned to dropbox. I will be taking extra precautions from now on. :) The LSC record will be updated back to the present over the next few days.

Australia continues to experience the effects of large East Coast Low's this winter... The past 6 years has seen an increase in low pressure systems and low pressure troughs that can create low pressure systems. The last 6 months has seen a peak in this activity so far. Ozone changes due to low UV output is probably the cause and with more to come with the declining SC24 which has seen F10.7 flux well below 100 for most of this year coupled with the predicted La Nina and Antarctic jet streams, we should expect a very cold 2016 winter in the southern hemisphere.
