Why is it important to know about the sun's sunspot cycle?

Question

Give two convincing reasons.

Answer 1

A sunspot is a blemish or dark spot on the sun and the area around it is actually brighter producing more energy from the sun. They are an example of solar convection and have strong magnetic field lines.

1. They seem to occur on an 11 year cycle. This has been observered over the last 60 years, but the cycle is an irratic one.
2. Sunspot activity activites more solar flares and an increase in the solar wind. Once this resulted in a black out that hit most of the Northeastern Coast of the US and Canada.

The last time we had a quite period the "Maunder Minimum in the 17th Century there were hardly any sunspots at all. This coincides with a period of cooling known as the Little Ice Age."

"Due to their link to other kinds of solar activity, sunspots can be used to predict the space weather and with it the state of the ionosphere. Thus, sunspots can help predict conditions of short-wave radio propagation or satellite communications."

Answer 2

Sunspot can cause severe electromagnetic disturbance on all electrical and electronics device causing power flunctuation, overloading powerlines creating brownout and destruction to electronics gadgets. Large dose of microwave energy such as x-ray are also release by sunspot occurences that people are advice to avoid sunbathing as this excessive energy can cause small amount of radiation.

So knowing its cycle help power companies to prepare for power surge and for people to avoid being expose to rays for a longer period of time.

Answer 3

the theory i discover maximum compelling regarding sunspots and cooling is by potential of Henrik Svensmark. He posits that once the solar is bare of spots, as that's now, the photograph voltaic wind is likewise waning which permits greater cosmic rays to hit the Earth and have interaction with our atmosphere, inflicting cloud formation. the added clouds have an basic cooling effect. We get comparable gamma radiation from the solar even though it has much less effect through fact that's much less lively, shifting at a slower velocity if I keep in mind the theory properly. CERN is going to objective his concept. I doubt this effect is sufficient to set off a return to the glacial element of our contemporary ice age, even though it ought to reason a sparkling Little Ice Age. nonetheless, by potential of many measures we are due for the return to the glacial point now and not something in our technology ought to sidestep it while it happens. right here is foodstuff for concept. CO2 is .04% of our atmosphere and reasons 9% or approximately 3C of the 33C warming that makes Earth liveable. on the instant value of improve, CO2 stages won't double till approximately 2250. yet they declare that increasing CO2, no longer even doubling the present quantity, will reason warming of as much as 8C by potential of 2100. that's a tragic day for technology while charlatans run the conferences and twaddle like it is taken care of as gospel. we are interior the 6th 300 and sixty 5 days of cooling in accordance to satellite tv for pc fact, yet they nevertheless yell approximately worldwide warming. no count how plenty CO2 we produce, maximum will flow into the oceans and we can't have the potential to stave off an ice age with one in each and every of those vulnerable gas. yet even with the cooling they're dumping lots of iron into the oceans to feed greater algae. i desire they do no longer flow too a ways as flora start to suffocate if CO2 stages decline too a ways decrease than what they have been in the process the Little Ice Age.

Answer 4

Astronots have to becarefull about sunsposts as well or they can be bombarded with lethal radiation.
