**** GEOMAGNETIC STORM BEGINNING ****

The ACE spacecraft, located approximately one million miles towards the Sun, detected a fast-moving ejection in
the solar wind at approximately 10:00 AM MDT today (1600 UT on April 6). This structure is believed to have
been launched from the Sun late on April 4. The Earth’s magnetic field responded shortly thereafter, and major
storm conditions are now occurring at all latitudes.

It is expected that this storm will continue for the next 24-36 hours. Significant impacts on terrestrial systems
include some electrical power systems, spacecraft operations, and communications and navigation systems.

In terms of the New NOAA Space Weather Scales, this storm may reach category G3 (strong) level.
