In this poster we discuss recent CDS and TRACE observations of a number of small and intermediate magnitude solar flares. In particular, we focus on a C3.0 flare which occurred on 26 March 2002 peaking at 15:21 UT. The event is first observed as two simultaneous foot-point brightenings in He I (584.33 A), followed by distinct loop-top emission visible in Fe XIX (592.16 A), which has a formation temperature of close to 10,000,000 K. As this high-temperature emission begins to cool, a cusp-shaped feature then becomes visible in Mg X (624.94 A) and Fe XVI (360.76 A). In addition to the morphology of the event seen in CDS and TRACE (171 A) images, a detailed analysis of CDS line parameters such as line position, width, and intensity is discussed in light of current solar flare models.
