NASA is reporting that the sun erupted with one of the largest solar flares of 
this solar cycle on March 6, 2012 at 7PM EST. This flare was categorized as an X5.4, making it the second largest flare — after an X6.9 on August 9, 2011 — since the sun’s activity segued into a period of relatively low activity called solar minimum in early 2007. The current increase in the number of X-class flares is part of the sun’s normal 11-year solar cycle, during which activity on the sun ramps up to solar maximum, which is expected to peak in late 2013. About an hour later, at 8:14 PM ET, March 6, the same region let loose an X1.3 class flare. An X1 is 5 times smaller than an X5 flare.
NPR is reporting that the flares will hit the earth on Thursday. The report goes on,”The flares took place about an hour apart. And when they hit Earth, the waves of magnetic fields may disrupt power grids, as well as radio-based communications. But the phenomenon might also bring auroras to the skies above residents of the northern United States, according to an interview with NASA solar physicist Alex Young, over at The Los Angeles Times.

NASA gathers information from the Solar Terrestrial Relations Observatory (STEREO) and the Solar Heliospheric Observatory (SOHO). In addition, last night’s flares have sent solar particles into Earth’s atmosphere, producing a moderate solar energetic particle event, also called a solar radiation storm. These particles have been detected by NASA’s SOHO and STEREO spacecraft, and NOAA’s GOES spacecraft.
US House Passes Hydropower Development and Rural Jobs Act
First, its all a guess but the sun will continue to shine for about theanor 2-4 billion years. So for all practical purposes, its eternal.Solar energy depends on sunshine, one disadvantage is cloudy, overcast, rainy, snow etc. days. No sunshine, no real energy. Another difficulty is converting solar energy, solar panels generate direct current (DC) and this has to be converted to AC current to run appliances, etc. in your house. In order to store solar energy, batteries are required, so the DC current from the solar panels can charge the batteries, and then the DC current must be converted to AC.Solar panels are not cheap but the price is coming down. They also don’t last forever and can be damaged by hail, etc.The good news is, solar energy is clean, not pollution except for the manufacture of the panels and for the moment, sunshine is still free.
