>You may be interested in receiving the new FREE  Internet information
>service offered by the Solar Terrestrial Dispatch (STD) on:
>
>(http://holly.cc.uleth.ca/solar/www/sublists.html
>
>The STD will e-mail you FREE any of the following products, as soon as
>they are prepared and posted:
>
>o  Daily Summaries of Solar and Geophysical Activity.
>       This most complete and detailed daily summary of solar activity,
>geomagnetic, activity and HF radio
>       propagation conditions available on the Internet. Includes
>72-hour forecasts. Recommended for all
>       serious radio amateurs, solar observers, and aurora hunters. 
>       
>o  Daily Summaries of Ionospheric Data.
>       For serious radio amateurs who need to receive complete
>ionospheric information from all reporting
>       ionospheric observatories around the world.
> 
>o  Daily Summaries of Auroral Activity.
>       The most complete database of auroral activity sightings in the
>world!
> 
>o  Daily Summaries of Solar WIND Spacecraft Data.
>       Solar Wind data such as solar wind velocities, densities, thermal
>temperatures, and Interplanetary
>
>o  Magnetic Field Data such as Bx, By, Bz, BT, Phi and Theta are given
>in graphical ASCII format in
>       these daily emailed products.
> 
>o  Weekly Solar Terrestrial Forecast
>       A very popular and useful weekly forecast of solar activity,
>geomagnetic activity, HF propagation
>       conditions (for high, middle and low latitude paths), and Auroral
>Activity. This product is updated
>       weekly and is valid for 10-days. Invaluable for radio
>communicators, aurora hunters, and solar
>       observers.
> 
>o  Potential Major Solar Flare Warnings and Alerts
>       Issued whenever active solar regions become capable of producing
>major solar flares. After a major
>       solar flare is observed, we issue a Major Solar Flare Alert that
>describes the event and provides a
>       preliminary Terrestrial Impact Assessment (forecast) for the
>event.
> 
>o Potential Geomagnetic Storm Warnings and Alerts
>       Issued whenever geomagnetic storms may develop, or whenever
>geomagnetic activity over middle
>       latitudes surpasses the Minor Storm threshold (A-Index of 30).
>Additional Alerts are issued if
>       geomagnetic activity reaches Major Storm levels (A-Index of 50)
>or Severe Storm Levels (A-Index of
>       100). Includes comprehensive information and forecasts. 
>       Potential Satellite Proton Event Warnings and Alerts
>       Issued whenever solar proton populations at geosynchronous
>satellite altitudes reach or exceed 10
>       particle flux units at greater than 10 MeV. Proton event warnings
>and alerts can be used by radio
>       communicators to determine when Polar Cap Absorption (PCA) may
>absorb polar-path HF radio
>       circuits. They can also be used by satellite operators to alert
>them to the potential of charging
>       anomalies on spacecraft.
> 
>o  Potential Satellite Anomaly Warnings
>       Issued whenever space environment conditions may become hazardous
>to orbiting satellite systems.
>       May include deep-dielectric charging anomaly warnings, surface
>charging anomaly warnings,
>       magnetopause crossing warnings, etc.
>
> o  Middle And Low Latitude Auroral Activity Watches and Warnings
>       Issued whenever auroral activity is expected to reach levels that
>may permit observation of visible
>       activity from the middle and/or low latitude regions. Watches are
>issued when activity may become
>       visible. Warnings are issued when activity has or is expected to
>become visible.
> 
>o  STD Administrative Bulletins
>       Issued by STD whenever users of our services need to be made
>aware of new information or changes
>       to existing information or services. You are automatically
>subscribed to this list if you subscribe to any
>       of the foregoing lists. It is compulsory for all users of our
>services to receive this product, so we can
>       make certain everyone stays informed.
