Here's the ESA site with info on 'Cluster'. Earth’s magnetosphere behaves like a sieve & Related articles [link to www.esa.int] Cluster overview, "Cluster is a constellation of four spacecraft flying in formation around Earth. They relay the most detailed information ever about how the solar wind affects our planet in three dimensions. The solar wind (the perpetual stream of subatomic particles given out by the Sun) can damage communications satellites and power stations on Earth. The original operation life-time of the Cluster mission ran from February 2001 to December 2005. However, in February 2005, ESA approved a mission extension from December 2005 to December 2009..."

Perhaps most surprising is that 8 May 2004 was just relatively a normal day for the Earth’s magnetic field. There were no large magnetic storms on Earth, or spectacular aurorae to fill the night sky.

Quoting: Anonymous Coward 3181070 located in fl, btw.. if that matters.. Viewing it from Tampa, it's going to be passing along pretty close to the ecliptic on it's way in. Right now it's coming up on Pollux & Castor. In fact, after it gets very close to Castor in January, it's going to stay pretty close to Castor until they both pass the Sun in July. Then it will move back the way it came, away from the Sun, and pass very close to Mars in Sept/Oct. After Oct '13, it will appear to change direction again and make a beeline for the Sun still staying pretty close to the ecliptic. After it passes the Sun it will head away at a sharp angle to the ecliptic as shown in the last video. |

Another. Cluster Observes a 'Porous' Magnetopause "The recently published paper in the Journal of Geophysical Research shows that the magnetopause - the outer region of the magnetic 'shield' around our planet - is breached in numerous places by the incoming charged particles of the solar wind. As a result, the boundary of Earth's magnetic bubble behaves more like a sieve than a continuous barrier that rebuffs the persistent onslaught of electrons and protons in the solar wind..."

It's one more leaf on the tree of knowledge. We weren't able to measure this type of process until very recently. Now we have a slightly better understanding of it from direct observations. I don't think you can classify knowledge as good or bad. "This discovery shows how Earth's magnetosphere can be penetrated by solar particles under certain interplanetary magnetic field conditions," said Matt Taylor, ESA project scientist for Cluster. "The study of the high-latitude, dayside magnetopause would not have been possible without the in situ measurements sent back by Cluster. The relatively small spatial separation of the four spacecraft made it possible to analyse the spatial structures and characteristics of KHW." These results are also relevant to studies of magnetospheric processes around other planets in the Solar System. For example, KHW and KH instabilities are commonly observed at the boundary of Mercury's magnetosphere and on the dawnward flank of Saturn's magnetopause. This new study opens up the possible locations where KHW may be generated, suggesting that they can be a common, and possibly continuous, mechanism for the entry of solar wind into planetary magnetospheres under various IMF orientations."

If it is a "common, and possibly continuous, mechanism", it means it's happened before, and it will happen again. Since nothing bad happened the last time, chances are nothing bad will happen the next time. Here is the TEC [link to www.haarp.alaska.edu] and another chart showing Electron Flux [link to www.swpc.noaa.gov] If you are talking about that one model that appears to have a problem, look at other models, or just another variant of the same model [link to www.ips.gov.au] |
