An Initiative to Predict Solar Flares Much in Advance



When solar flares occur, their dangerous radiations imperil satellites, astronauts, and power grids. In order to warn them in advance so that they could take

sufficient precautions, U. S. scientists have developed a new method, which will help them, forecast solar flares more than a day before their actual

occurrence.

When atoms in radioactive elements decay or lose their energy, they produce gamma radiations. This newly derived system will measure the difference in these

gamma radiations and will indicate the occurrence of solar flares. The main theory behind this system is that the rates with which radioactive elements

decay, depends upon any kind of activity that takes place in the solar system and this most of the times could be brooks of subatomic particles, known as

solar neutrinos.

Ephraim Fischbach, a Purdue University professor of physics said, "This influence can wax and wane due to seasonal changes in Earth's distance from the sun

and also during solar flares".

Solar flare is a condition, when suddenly huge amount of energy discharging lightening is observed over the Sun's surface or the solar limb. According to

scientists, it is generally 36 hours prior the beginning of a solar flare, when radioactive samples start varying.
