- EIT
-
- EIT (Extreme ultraviolet Imaging Telescope) is designed to study features (coronal holes, coronal bright points, active
- regions, filaments, &c.) visible in the 0.9 - 2.5 MK plasma in the low corona, and similar features visible in the
- transition region at temperatures ~ 80,000 K. Serendipitously, with additional telemetry bandwidth discovered by the
- spacecraft engineers, EIT was able to discover 'Moreton waves' - the signature of coronal mass ejections (CMEs) in the
- lower corona.
- EIT is able to image the solar transition region and inner corona in four, selected bandpasses in the extreme ultraviolet
- (EUV):
- Fe IX/X, 171 ≈
- Fe XII, 195 ≈
- Fe XV, 284 ≈
- He II, 304 ≈

- CONNECTION WITH OTHER INSTRUMENTS
- The instrument was designed to be used in conjunction with other SOHO instruments particularly the LASCO visible-
- light coronagraphs and the SUMER and CDS imaging spectrographs, as well as with ground-based instruments.
