Topband: ACE real time solar wind pages

[Dr. Wolf Ostwald]

hi all !
Thanks much for all the responses.
The easiest to comprehend graphics i found are here : 
http://www.swpc.noaa.gov/SWN/
It has a three picture window called   "ACE real time solar wind pages"
The one on the left shows the Inklination of the interplanetary mag 
field (which is generated by the solar wind ) against the earths own mag 
field.
Whenever both are similarly polarized,, even slow winds ( up to 400 
km/sec ) can trash MF prop. When strong solar winds prevail, 
polarization is no longer important.
That seems to be the common conception.
