Dear John,

    I sent this to Magnet a week or so ago..... You might be interested.....

    Measurement of the Earth's magnetic and electric fields are used for a

number of purposes, Navigation, Radio Propagation, Auroral studies, Meteor

studies, error signals in seismometers, Earthquake 'prediction', etc, and

there are a variety of Websites which give relevant information.

    This includes magnetograms, pulsations, ULF radio, sky cameras, aurorae

riometer, radar, MUF, E Field, data on the magnetosphere and space 'weather',

equipment of various kinds, methods of observation.....

    The European Magnetometry Sites are covered by the SAMNET in the UK,

IMAGE and MIRACLE chains of sites in Scandanavia and by DK0WCY in Germany.

    The SAMNET magnetometry array is at

http://samsun.york.ac.uk/samnet_home.html . There is a map of the stations.

Realtime Variometer outputs for X & Y for today are given and the X, Y & Z

graphs for yesterday for five stations are also displayed. Archive traces are

available.

    The IMAGE network of 25 stations is at

http://www.geo.fmi.fi/image/index.html and again has archive material as well

as real time data.

    There are links to the MIRACLE network at http://www.geo.fmi.fi/MIRACLE/

. This has Magnetometry links including magnetic pulse FFT's, Sky Cameras and

Radar.

    DK0WCY gives a realtime magnetograms and various other information

related to Radio at http://www.dk0wcy.de./ This is the most southerly station.

    Radio related information links are provided by the Radio Society of

Great Britain at www.rsgb.org/society/psc.htm including auroral propagation

and meteor scatter. The Propagation Studies Webpage is at

http://www.keele.ac.uk/depts/por/psc.htm

    The Magnetic Observatories main page is at

http://geomag.usgs.gov/frames/mag_obs.htm

    The GEOMAGNETIC DATABASE is at http://www-ssc.igpp.ucla.edu/gem/geomag/

    Space weather is at http://www.spaceweather.com/

    There is a HUGE LIST of Auroral, Magnetometry and other Websites on N1BUG

Web : Homepage at http://aurora.n1bug.net/ This includes all the US and

Canadian sites and there are several that have educational / historical /

scientific articles.  (Not working on 4/29/2006.)

    Some Australian / NZ data is at http://plasma.newcastle.edu.au/spwg/ It

includes VLF radio, radar and there is a tutorial about the magnetosphere.

Flinders is at http://gaea.es.flinders.edu.au/~mgfhc/RealMagnetogram.htm and

the IPS support page listing a lot of other sites / data types is at

http://www.ips.gov.au/Main.php?CatID=8

    Auroral Pictures and links can be found at

http://www.geo.mtu.edu/weather/aurora/

    Low frequency Earth / Radio waves are also studied by the Elfrad group

www.elfrad.com/ as precursors to seismic events.

    A VLF electric field probe receiver and a host of recordings of

lightning, whistlers, auroral and meteor signals / effects are at

http://www.triax.com/vlfradio/natradio.htm (This site is now missing.  If anyone knows where it went to, please let me know.  Thanks, John)

    The Astroweb astronomy database is at

http://www.stsci.edu/astroweb/astronomy.html and there is more information on

the astronomy ftp sites file at

ftp://seds.lpl.arizona.edu/pub/faq/astroftp.html

    I hope that these varied references are of interest..... It's a Big World

out there....
