Sun Spot

Sunspot

Studies of stratigraphic data suggest that solar cycles have been mobile for cs of millions of years, if not longer, measuring varves in sedimentary rock has revealed repeating peaks in layer thickness, at eleven-year intervals.
Without these constant cycles there would not be any macules produced.
The earliest record of macule observation is date all the way back to 364 BC, based on comments by Chinese astronomer Gan De in a star catalogue. By 28 BC, Chinese astronomers were regularly recording sunspot observations in official imperial records to gain more information on them and to have records to keep track of them by.
The first clear take down of a sunspot in Western literature was on 17 March, 807 AD by the Benedictine monk Adelmus, who discover a large sunspot which was visible for eight days.

Sunspots ar only temporary phenomena on the photosphere of the Sun that appear visibly as dark spots comp ared to other surrounding regions on the sun.
Sunspots are caused by an incredible amount of magnetic activity, which causes an keen amount of heat, forming areas of reduced surface temperature.
The average temperature of a sunspot cornerstone be anywhere in the range from 2,7274,227 °C.



If a sunspot were isolated from the surrounding photosphere it would be brighter than an electric arc. Sunspots wave and contract as they move across the surface of the Sun.
They can be as large as 49,710 mi in diameter, making the larger ones visible from Earth without the aid of a telescope. They also travel at speeds of a few hundred meters per second when they emerge onto the solar photosphere.
Not only do sunspots appear as a great phenomenon, they also are followed by a secondary phenomenon known as lei loops.

Most of the coronal loops originate in magnetically active parts around the visible sunspot groupings.
Although many of the sunspot phenomenons appear to look the same, sunspots have 11 several(predicate) stages in which they cycle...If you want to get a full essay, localize it on our website: Orderessay
