Solar Mass Ejection Imager

SMEI Camera Module CGI


SMEI is an instrument designed to detect the transient clouds of hot ionized gases which are emitted by the sun from time to time. Of particular interest are those clouds that are coming towards the earth, as they can have a serious effect on earth-orbiting satellites, electrical power distribution networks and long distance radio.

The SMEI team comprises the following individuals:

Other participants have included S. Keil (National Solar Observatory), S. Kahler, R. Altrock (AFRL), and P. Anderson (BU).


The SMEI instrument was delivered on time and integrated to the spacecraft in late April 2001.

This mission was launched from Vandenberg Air Force Base, on January 6th, 2003, at 14:19am GMT. The satellite completed initial checkout on February 6th, 2003, and is currently running normal operations. A first light all-sky map was produced from the very early data.
