The Sun is approaching Solar Maximum, expected to occur in 2013. Was March 7th X5.4 solar flare an indication of things to come? “During a powerful solar blast in March, NASA’s Fermi Gamma-ray Space Telescope detected the highest-energy light ever associated with an eruption on the sun,” states the video summary. “The powerful March 7 flare… is the strongest eruption so far observed by Fermi’s LAT [Large Area Telescope]. The flare produced such an outpouring of gamma rays – a form of light with even greater energy than X-rays… At the flare’s peak, the LAT detected gamma rays with two billion times the energy of visible light, or about 4 billion electron volts (GeV), easily setting a record for the highest-energy light ever detected during or just after a solar flare. The flux of high-energy gamma rays, defined as those with energies beyond 100 million electron volts (MeV), was 1,000 times greater than the sun’s steady output… The March 7 flare also is notable for the persistence of its gamma-ray emission. Fermi’s LAT detected high-energy gamma rays for about 20 hours, two and a half times longer than any event on record… Solar eruptions are now on the rise as the sun progresses toward the peak of its roughly 11-year-long activity cycle, now expected in mid-2013.” Is this just the beginning of an unimaginable increase in solar activity?
