>
>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
