And some facts according to NASA
This video is very interesting; the commentator explains that the ‘experts’ conception of the boomerang of the comet around the sun may be incorrect. That the debris field may be a significant concern IF the comet takes a southerly track around the sun.
A Sungrazer comet could bring a meltdown of satellite technology and otherwise cause a technical Armageddon across Earth. Its potential effects have been compared to consequences associated with electromagnetic pulse [EMP] weapons or a full-scale nuclear exchange.
David Eichler, lead author of a forthcoming Astrophysical Journal Letters paper, is theorizing that a sun-grazing comet roughly the size of Hale-Bopp (with a nucleus some 30 kms in diameter), could trigger cosmic ray-generating shockwaves large enough to initiate a complete global electromagnetic meltdown. Eichler is an astrophysicist at Israel’s Ben-Gurion University. Eichlet feels that satellites could be put in protection mode but would otherwise be destroyed as Sungrazer ISON passes. Earth’s electronics, from micro-circuitry on cellular phones to large power stations, could become non-functional.
If such a comet were the size of Hale-Bopp, Eichler says, the resulting solar flare would by far be the largest ever experienced. A comet gets compressed and then explodes in the solar atmosphere which, in turn, creates shockwaves and a gigantic solar flare. There is evidence that a sun-grazing comet may have triggered a large solar flare and cosmic ray-generating shockwaves as recently as 775 A.D., as indicated by tree ring analysis.
ISON is smaller than Hale-Bopp and the 775 A.D. comet; apparently the earth’s only hope.http://ufodigest.com/article/comet-ison-sungrazer-coming-will-it-cause-solar-flare-and-electronics-meltdown
