The number of contraband spots peppering the sun ’s Earth’s surface in August was the high for almost 23 years , unexampled data point show . The latest sunspot enumeration was more than twice as high-pitched as initial forecasts promise and is another open planetary house that the sun ’s explosive peak , or solar maximum , is likely well afoot — andwill be far more active than scientists ab initio thought .
Sunspots are regions of the sun ’s surface where surges of electromagnetic actinotherapy break through the star ’s magnetic field , creating comparatively cool patches thatappear disastrous to us thanks to an optical phantasy . Along with the size and frequency ofsolar flaresandcoronal mass ejections , sunspot numbers indicate the forward motion of the sun ’s roughly 11 - twelvemonth solar cycle .
There was an average of 215.5 daily sunspots on the sun’s surface during August. This time-lapse image shows every visible dark patch moving across the sun during this time.
During the Sunday ’s least participating phase angle , or solar minimum , there are very few or occasionally no sunspot . For example , in late 2019 , in brief before the starting time of the current solar cycle ( Solar Cycle 25 ) , there were40 consecutive days with no seeable sunspots . But as the Sunday ’s magnetic field gets entangled with itself and weakens , sunspot identification number apace wax before peaking during solar utmost . During this active phase , the Dominicus ’s magnetised field eventually snaps and completely flips , which touch off a strike - off period of solar bodily process and a decrease in sunspots until the whole cycle restarts .
In August , there was an norm of 215.5 daily sunspots on our place star ’s surface , concord to theSpace Weather Prediction Center ( SWPC ) , which is jointly run by the National Oceanic and Atmospheric Administration and the National Weather Service . The last clock time the monthly macula number was this high was September 2001 , during the solar maximum of Solar Cycle 23 , when the average was 238.2 .
The routine of macula peak on Aug. 8 , when up to 337 sunspots were observed on the sun , which is thehighest sum in a 24 - time of day period since March 2001 .
The latest monthly sunspot count is the highest since September 2001. Here we can see the all the monthly values back to around 1950.
These numbers betoken what some scientists have already surmise — thatwe have accede solar maximum . However , we ca n’t be sure of this until long after macula numbers lead off to put down again .

When the current solar cycles/second start in 2020 , a panel of SWPC scientists predicted that Solar Cycle 25 would be relatively weak compared with historic Hz , much like Solar Cycle 24 , which peaked around 2014 and was the debile uttermost for around 90 year . For example , the average macula number presage for August 2024 was 107.8 , which is less than half the actual number that has just been released .
Massive dark spots were visible on the sun in most photographs from Earth in August. This photo was taken from New York City on Aug. 24.
The SWPC prognosis also suggested that the solar maximum would probably not arrive until 2025 .
However , from ahead of time on in the current cycles/second , the macula routine have not match the initial forecast . The figure began to climb in early 2022,reaching an eight - year high by the end of the year . By June 2023 , the norm numbersurpassed any of the months from Solar Cycle 24and has increased ever since .
As a effect , SWPCreleased a " revise prognostication " for Solar Cycle 25 in October last year , which forecast that solar maximum would in all probability arrive by mid-2024 and be more dynamic than expect .
Rising macula numbers are not the only indication that we are now living through solar maximum . In former May , Earth was hit with themost knock-down geomagnetic storm for more than 21 years , whichpainted an abnormally large portion of the major planet ’s skies with auroras . And just a few days later , our home starspat out an X8.7 magnitude solar flare — the most powerful solar explosion since 2017 .

Solar maximums can last for one to two years or more , meaning there is still a becoming prospect that activity will continue to storm up over the next 12 calendar month or so . During Solar Cycle 23 , macula Book of Numbers peaked at a maximal monthly value of 244.3 in July 2000 . And in Solar Cycle 22 , the monthly record was 284.5 in June 1989 .
If solar activity continues to increase and Earth is bombarded with more knock-down solar storm , like the1859 Carrington Event , it couldimpact basis - based substructure , trigger widespread sunrise at depleted latitudes andcause satellites to tumble back to Earth .
