Anybody able to comment on the radiation absorption map? How is it that it all dissappears so rapidly? I mean dang...one day the planet is inundated at the poles and waves are reaching clear into the adjacent continents...and today it's all gone!
Quoting: Idgits [ link to www.swpc.noaa.gov] Hope i can help. But i'm still learning. Generally absorption is from solar winds. When a CME passes, the dense wave usually pushes all material in space with it and creates a gap in behind the wave, similar to moving your hand through water or air creates a pocket in behind it. That could be why after the CME reached earth, we can see a sudden drop off in absorption. Hope i explained well enough. This current simulation should help visualising what i'm trying to describe. [ link to www.swpc.noaa.gov] Can a CME gather up debris? Like dust, meteors, space junk, etc? If so, could it theoretically hurl it towards earth? I don't know if 'hurl' is the right word, but a gentle nudge, sure. CME's definately gather dust and recently the predictions of the trajectories of the falling satellites such as UARS and ROSAT have been adjusted to account for solar winds. They certainly influence satellites. Meteors, sure, but the larger the mass, i assume, the more difficult it would be to change the trajectory.
