The Extreme Ultraviolet Imager (EUVI) is part of the SECCHI investigation selected for flight on the STEREO mission. The twin EUVI telescopes on the two STEREO spacecraft will study the structure and evolution of the solar corona in three dimensions, and specifically focus on the initiation and early evolution of coronal mass ejections (CMEs).
The EUVI's 2048 x 2048 pixel detectors will have a full sun field of view, and will observe in four spectral channels that cover the 0.1 to 2 MK temperature range. The EUVI's major advance is its view from two vantage points in space. It will allow it to investigate the structure of CMEs in three dimensions, while the EUVI's high image cadence capability will allow it to resolve the CME's initiation and early evolution.
