Scientific paper

The TRACE data set provides a view of the solar atmosphere from the photosphere in white light, through the transition region in ultraviolet wavelengths, and into the corona in extreme ultraviolet wavelengths (EUV). From May 16-23, 2000 TRACE and MDI/SOHO observed at least 3 rotating sunspots in AR9002 and AR9004 at several wavelengths. Over this time period several small flares, along with a CME on May 23, occurred in these regions. In addition we have potential-field renderings of the coronal magnetic fields for the TRACE pointings, extrapolated based on the Virtual Starlab forecaster data, which in turn has been generated from the MDI/SOHO observations. An analysis of the rotating sunspots, together with images and movies, will be provided for these active regions, accompanied by images of the extrapolated coronal magnetic fields for comparison with images of the TRACE 1-1.5 MK EUV loops. This work was supported by NASA, in part under the TRACE contract NAS5-38099 and in part under the MDI/SOHO contract NAG5-13261.
