Solar flare is a large explosion in Sun's atmosphere which can make a huge energy. Solar flares effects all layers of solar atmosphere. In the middle of the millennium year our earth come into a period called solar maximum. Means the activity of our sun grow up so fast.The effect is solar flare with a highest intensity. there are many solar flare that was happen in this century, some of source says that.
It will effects our activity in the earth. The simple one is natural navigation like dove to find it home or another place, electricity, even telecommunication were damage. Flares are powered by the sudden release of magnetic energy stored in the corona. If a solar flare is exceptionally powerful, it can cause coronal mass ejections.
Richard Christopher Carrington were the first one who observed solar flare and independently by Richard Hodgson in 1859. The frequency of occurrence of solar flares varies from several per day when the sun is particularly "active"to less than one each week when the sun is "quiet". Large flares are less frequent than smaller ones. Solar activity varies with an 11 year cycle.At the peak of the cycle there are typically more sunspotson the sun, and hence more solar flares.
THE CLASSIFICATION OF SOLAR FLARE
Solar flares are classified as A, B, C, M or X according to the peak flux (in watts per square meter, W/m²) of 100 to 800 picometer X-rays near Earth, as measured on the GOES spacecraft. Each class has a Peak flux ten times greater than the preceding one, with X class flares having a peak flux of order 10−4 W/m². Within a class there is a linear scale from 1 to 9, so an X2 flare is twice as powerful as an X1 flare, and is four times more powerful than an M5 flare. The more powerful M and X class flares are often associated with a variety of effects on the near-Earth space environment. Although the GOES classification is commonly used to indicate the size of a flare, it is only one measure. This extended logarithmic classification is necessary because the total energies of flares range over many orders of magnitude, following a uniform distribution with flare frequency roughly proportional to the inverse of the total energy. Stellar flares (and earthquakes) show similar power-law distributions.
Solar flares release a cascade of high energy particles known as a proton storm. Protons can pass through the human body, doing biochemical damage. The proton storms are produced in the solar wind, and hence present a hazard to astronauts during interplanetary travel. Most proton storms take two or more hours from the time of visual detection to reach Earth's orbit. A solar flare on January 20, 2005 released the highest concentration of protons ever directly measured, taking only 15 minutes after observation to reach Earth, indicating a velocity of approximately one-half light speed.
