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.

July 2014 News

July Update:  This month saw a small increase in activity with the southern hemisphere continuing to dominate with about 65% of the activity recorded in the south, but the month overall was a mixture of higher activity and 5 spotless days. The speck ratio staying around the 0.6 level and overall SC24 continues to demonstrate the higher proportion of small spots to large spots during SC24, if we take away the small spots counted in passing groups the ratio would be much higher. The LSC was measured at 40.84, SIDC 72.5, NOAA unadjusted at 113.6 (prov). NOAA this month again counting less than the SIDC.

The SIDC/NOAA and LSC/SIDC comparison graph showing a growing difference with the general trend continuing to rise over SC24.                                             

SC24 is still on track to be a lower cycle than SC5.
