Can you live your life without mobiles, Internet, Metro life and all those which need Solar power, energy to being work. According to ISRO the black area which is recently saw on SUN is very serious matter to discuss, because its must being a very critical situation for whole world.
The sun’s activity during the cycle, which is 24th in the last 250 years, will be low initially but intensify to its peak in 2011-12 when frequent solar flares and magnetic storms could occur disrupting satellite communications and power grids.
The solar cycle occurs due to changes in sunspots.
The solar physicists spotted changes in alignment in sunspots which marked the beginning of the new cycle.
The cycle reverses the north and South Pole of the sun leading to changes in magnetic field.
A study by scientists last year revealed that this solar cycle will be 30 to 50 per cent stronger than the previous one which ended on Friday.
Though the average solar cycle is for 11 years, it could range from 9 to 14 years.
With the emergence of magnetically reversed high-latitude sunspot today, NASA’s solar physicists described it as the beginning of the next 11-year solar cycle.
"Solar physicists have been waiting for the appearance of a reversed-polarity sunspot to signal the start of the next solar cycle and the wait is over," the scientists said in the space weather alert bulletin.
The solar magnetic activity cycle is the dynamical engine and energy source behind all solar phenomena driving space weather.
The solar cycle was discovered in 1843 by Samuel Heinrich Schwab.
Indian Space Research Organization (ISRO) officials said they may contemplate shutting non-essential gadgets on the satellite to reduce the affect of solar flares.
"In case of increase of Coronal Mass Ejection (CME), scientists may contemplate shutting non-essential circuits and gadgets like cameras on the satellite to protect them," an ISRO official said.
