Video/Photo: Solar explosion 2012, the most powerful sun blast in the past 7 years
NASA released the first images of today’s solar storm, initially seen as the strongest since 2005 but after the last updates (sun’s radiation burst) is now considered the largest since October 2003 (scroll down for 2012 solar eruption videos and photos).

Astronomers already issued a warning on Monday, especially because last time when a similar phenomenon occurred was in 2005. Plasma expelled from the Sun’s crown will lead to the formation of geomagnetic storms: practically Earth’s magnetic field will be saturated, fact which affects the operation of satellites as well as the telecommunications and modern technology
NASA’s Solar Dynamics Observatory, Solar Heliosphere Observatory (SOHO) and spacecraft Stereo, captured the solar explosion on Sunday 22 January, when the sun erupted with an M8.7 class flare, an earth-directed coronal mass ejection (CME), and a burst of fast moving, highly energetic protons known as a “solar energetic particle” event.

According to information provided by the National Oceanic and Atmospheric Administration (NOAA), the intensity of the solar flare and the amount of spewed radiation have not reached this magnitude since May 2005. Kathryn Sullivan, Deputy Secretary for NOAA, said the planes circling Earth through the poles will be rerouted for several hours. Usually, such astronomical phenomena are known to cause problems to aircraft communications. Physicist Doug Biesecker of the Space Weather Prediction Center in Colorado, USA, quoted by Washington Post, confirmed this, adding that flights between North America and Europe or Asia will be diverted because of high levels of radiation emitted after Sun’s storm. “It’s not gonna be a catastrophe, although the influence of the geomagnetic current on the electrical grid will be noticeable,” said Michael Hess, a NASA expert.
Some of these causes modify the central nervous system’s response which inhibits erection by denying blood supply or by altering nerve cheapest levitra activity. There is basic difference tadalafil online usa between this particular drug and the other PDE-5 inhibitors can help men with erectile dysfunction (male impotence) by enhancing the erectile response when a man is sexually stimulated, an erection is produced via a complex chain of events, which involved signals from the nervous system and right to the release of chemical messengers within the tissues of the penis.

The solar explosion will affect electricity networks as well as global positioning systems, known as GPS. There will be a pulsed radiation heading toward our planet at a speed of over 2,000 kilometers per second, writes Gizmodo.

The storm disrupted the air traffic and is already possible to affect satellites, due to exposure to proton fluxes, which disrupt the high frequency communication systems. Given that radio waves are vital because they can keep aircrafts in touch with control towers, all flights near areas (e.g. Poles) where Earth’s magnetic field is exposed to radiation have been diverted.

Technical difficultiesHigh radiation levels willmake board computers to reset, generators to scramble, and telemetry data to change. All these changes could overturn the entire spatial system. GPS systems are also hit and the effect will be seen especially on Wednesday. Although we can still use car’s or mobile phone’s GPS without any problems, the troubles mainly refer to those who must use high precision guidance systems, such as the military ones.
Biological HazardsThe S3-ranked proton storm could jeopardize the passengers on the planes flying beyond the parallel 65 in the northern hemisphere. For this reason, all routes will be diverted to lower latitudes to avoid any discomfort caused by radiation.
Visual spectacleThe geomagnetic storm caused by the penetrating solar radiation will create spectacular lights in the sky as auroras borealis. Unlike normal auroras, these ones are visible even in New York, Michigan or Maine, which are located at much lower latitudes usual for auroras.
