ACE Solar Wind 1 min
====================

.. contents:: Table of contents

The location of the NASA Advanced Composition Explorer (ACE) satellite at the L1 libration point between the Earth and the Sun, about 1,500,000 km forward of Earth, enables ACE to give up to one-hour advance warning of the arrival of damaging space weather events at Earth. The Solar Wind Electron Proton Alpha Monitor (SWEPAM) experiment provides the bulk solar wind observations for ACE.
