Following is a comparison of the growth of cycle 25 versus cycle 24, using the 13-month sunspot averages, beginning with the months of the respective minimums. Numbers in brackets for cycle 25 indicate the minimum possible value for that month, assuming there are no more sunspots between now (Dec 6, 2024) and six months after the end of the ...
Solar cycle 23 lasted 11.6 years, beginning in May 1996 and ending in January 2008. The maximum smoothed sunspot number (monthly number of sunspots averaged over a twelve-month period) observed during the solar cycle was 120.8 (March 2000), and the minimum was 1.7. [29] A total of 805 days had no sunspots during this cycle. [30] [31] [32]
At a solar-cycle minimum, the toroidal field is, correspondingly, at minimum strength, sunspots are few in number, and the poloidal field is at its maximum strength. With the rise of the next 11-year sunspot cycle, magnetic energy shifts back from the poloidal to the toroidal field, but with a polarity that is opposite to the previous cycle.
The sun emits the largest solar flare of this 11-year cycle, as imaged by NASA's Solar Dynamics Observatory on October 3. NASA/SDO NASA says the sun is in the highly active "maximum phase" of its ...

Changes of 3–4% in cloudiness and concurrent changes in cloud top temperatures correlated to the 11 and 22-year solar (sunspot) cycles, with increased GCR levels during "antiparallel" cycles. [96] Global average cloud cover change was measured at 1.5–2%.
Generally, senior dogs are more likely to develop cancer than younger ones. According to the American Veterinary Medical Association (AVMA) , about half of dogs over 10 will develop cancer.
In one study, 45% of the dogs that reached 10 years of age or older died of cancer. [ 1 ] Skin tumors are the most frequently diagnosed type of tumor in domestic animals for two reasons: 1. constant exposure of animal skin to the sun and external environment, 2. skin tumors are easy to see because they are on the outside of the animal.
