"Telamon" sprache http://www.space.com/scienceastronom...lar_storm.html Watch this page: http://www.sec.noaa.gov/SWN/index.html Pay attention to the Magnetic Field Bz component dial. As it looks at this very moment, it shows a slightly reversed (S) magnetic field relative to earth's N/S magnetic poles. If this trend continues geomagnetic activity will increase. See http://www.sec.noaa.gov/SWN/sw_dials.html Magnetic Field Bz dial: Ranges from -50 to +50 nT. The dial is a linear scale from -10 to +10 nT and a different linear scale from -10 to -50 nT and +10 to +50 nT. For values beyond the maximum and minimum, the arrow will stay pegged at the maximum or minimum. If the magnetic field data are missing, the arrow will not appear. The arrow will move to the location on the scale corresponding to the actual value of the latest 15 minute average of the Bz component of the magnetic field vector. The letters N and S refer to North and South of the magnetic equator. The color bar indicates green for positive values, yellow for small negative values , and red for large negative values of Bz. Why Bz is so important: When the interplanetary magnetic field turns south compared to the Earth's magnetic field, geomagnetic activity will increase. As the Bz (Southward pointed) value becomes more negative, the associated geomagnetic activity increases. |

I'm no expert in this sort of thing but my understanding is that voltages are induced of long conductors such as the power grid with its many miles of lines and oil or gas systems with its many miles of pipes. These induced voltages can drive destructive currents in the aforementioned systems. -- Telamon Ventura, California |

All shortwave listeners should do this. -- Telamon Ventura, California |

Do you have a little Compass? Set it some where and watch to see if the
needle jumps around. cuhulin |

Telamon,
Conditions here in Uxbridge, MA were very good last (Thursday) night. Actually I was thinking the best I have had here - I am a newbie so maybe easily impressed - dunno. Likewise early Thursday at sunup they were very good. Does yesterday's magnetic index support the clear long bands I had here? 73 NEO Telamon wrote: http://www.space.com/scienceastronom...lar_storm.html -- Telamon Ventura, California |
