[17.04] Moss Loop Cooling in the TRACE 171A Passband

There is clear evidence that ``moss'' (hot, low-altitude plasma seen in the 171Åpassband of the Transition Region and Coronal Explorer) is transition region emission at the footpoints of hot (~ 3-5 MK) coronal loops overlying plage regions. Since the radiative cooling time for these loops (> 10 minutes) is greater than TRACE's typical cadence in 171Å, one expects to observe these loops cool through the passband as the moss boundary evolves. This poster reports on our study of the co-evolution of moss/plage boundaries with cooling loops.

TRACE is supported by contract NAS 5-38099 from NASA to LMATC.
