A sunspot four time the size of the Earth is make its mode across the Sun at the second . The spot is so with child you could see it without a scope , though of class you should use protective equipment .
macula AR3310 should be seeable to you using solar viewing glasses , those nerveless disposable shades you foolhardily discombobulate off after the lasteclipse . sunspot are areas of theSunthat seem darker due to a slightly lower temperature .
" Sunspots are areas where the magnetized landing field is about 2,500 prison term stronger than Earth ’s , much gamey than anywhere else on the Sun , " theNational Weather Serviceexplains . " Because of the strong charismatic area , the magnetised pressure increase while the surround atmospheric pressure fall . This in turn lowers the temperature relative to its milieu because the hard magnetic subject inhibits the rate of flow of hot , new gas from the Sun ’s Department of the Interior to the surface . "
Sunday activeness increment and decreases in a 11 - yr cycle known as theSchwabe cycle . From 1826 to 1843 , German amateur astronomer Heinrich Schwabe note the Sun , come upon that it rotates on its axis once every27 days . He noticed the Sun goes from quiet periods , where no macula can be see , to the maximum form where 20 or more groups of sunspot can be seen .
The Sun ’s activity is increasing at the moment , with the next solar maximum predicted to be around July 2025 , according toNASA . However another squad believes that they have abetter predictionby looking at magnetised doughnut which mould at 55 degree of latitude on both hemispheres of the Sun . These formations transmigrate towards the equator where they meet and invalidate each other out , which the team knight a Hale cycle terminator .
This eradicator effect tend to happen up to two long time after the minimum , and by focusing on these events the team believed they could make upright prevision about the solar cycles .
" If you measure how long a wheel is , not the minimum to minimum , but from terminator to terminator , you see that there is a strong linear relationship between how long one wheel is and how strong the next one is lead to be , " NASA research scientist Robert Leamon toldSpace.com .
Using the approach , they foretell that the next solar maximum will take place a yr earlier , in mid-2024 . But you do n’t have to wait that long to see an awesome macula .
