Summary

Abstract: Advanced Composition Explorer (ACE) Real-Time Solar Wind (RTSW) Data from
NOAA's Space Environment Center (SEC) provides up to an hour's advance warning
of unusual solar activity, such as solar flares and coronal mass ejections,
which can cause geomagnetic storms.

Geomagnetic storms are a natural hazard, like hurricanes and tsunamis, which
the National Oceanic and Atmospheric Administration (NOAA) Space Environment
Center (SEC) forecasts for the public's benefit. Severe geomagnetic storms
cause communications problems, abruptly increase drag on spacecraft, and can
cause electric utility blackouts over a wide area. The location of ACE at the
L1 libration point between the earth and the sun will enable ACE to give about
a one hour advance warning of impending geomagnetic activity.

NOAA has arranged for the transmission of a subset of data from four ACE
instruments during the times when ACE is not transmitting it's full telemetry
to the Deep Space Network. For about 21 of 24 hours per day, ACE will send data
(~464 bps) to NOAA operated ground stations. During the other three hours when
NASA is getting high rate data through the Deep Space Network, NOAA will get a
copy of the real time data. NOAA will process all the data (using algorithms
provided by the ACE experimenters) at its Space Weather Operations (SWO) in
Boulder, Colorado, which will issue any warnings of expected geomagnetic
activity.

The four ACE instruments and the data they will supply are:
EPAM - Energetic Ions and Electrons
MAG - Magnetic Field Vectors
SIS - High Energy Particle Fluxes
SWEPAM - Solar Wind Ions

The data consists of:
Dynamic RTSW plots including magnetic and plasma fields, low and high energy
electrons and protons
Real time 1 and 5 minute data
Hourly data
