This visualization compares the full-disk solar view of SOHO/EIT (green, on the left) with the small field of view of the TRACE ultraviolet telescope (gold, on the right). The yellow border of the TRACE imagery is projected on the appropriate location on the green EIT imagery.

Notice that TRACE can track features as they move across the solar disk. The instrument pointing is adjusted on a regular basis, which can produce a considerable amount of jittering in the image.

This is a variation on the treatment of the same data as Solar Dynamics Observatory (SDO): Data Collection Comparison.

Note that this movie does not play synchronous with the other animations that are part of the SDO Prelaunch package.
