ocr: EIT EIT (Extreme ultraviolet maging Telescope) is designed to study features (coronal holes, coronal bright points, active regions, fila- ments, &c.) visible in the 0.9-2.5 MK plasma in the low corona, and similar features visible in the transition region at remperatures - 80,000 K. Serendipitously, with additional telemetry bandwidth discovered by ther spacecratt engineers, EIT was able to discover Moreton waves'- the signature of coronal mass ejections (CMES) int the lower corona. EITi is able to image the solar transition region and inner corona in four, selected bandpasses in the extreme u ...
