Studying transition region phenomena with Solar-B

Peter Young

Spectrometers onboard SOHO have revealed a wealth of dynamic phenomena occurring in the Sun's transition region, with CDS and SUMER demonstrating rapid intensity fluctuations, high velocities and non-thermal broadening in blinkers and explosive events. The high spatial resolution of the SOT and vector magnetograph capability of the FPP potentially allow the transition region phenomena to be related to variations in the magnetic field, however the EUV spectrometer (EIS) has been optimised for coronal observations. This presentation will argue that good transition region science is possible with EIS in active regions and that, coupled with coronal observations from XRT and EIS, and photospheric observations with SOT/FPP, excellent opportunities exist to expand upon the work with SOHO and place the transition region phenomena in context. In particular I consider possibilities for studying loop footpoints, and active region blinkers.
