WE PROPOSE TO OBSERVE A NEW X-RAY BRIGHT T-TAURI STAR IN SEO CEN (LOG10 LX - 30.4 ERG/S). THE LARGE FLUX MAKES THIS SOURCE A PRIME XMM-NEWTON/RGS TARGET. WE REQUEST A 65KS OBSERVATION OF SWIFT J122825.9-632100 WITH THE RGS ON XMM-NEWTON (50 KS GOODTIME&15 KS FLARING OVERHEAD). THE PROPOSED OBSERVATIONS WILL DETECT THE DENSITY AND TEMPERATURE SENSITIVE HELIUM- LIKE NE IX AND MG XI TRIPLETS AND PLACE A STRINGENT LIMIT ON THE PRESENCE OF D VII EMISSION (FO VII 2E-6 PHOTONS/S/CM-2) PROVIDING UNIQUE CONSTRAINTS ON THE ACCRETION FLOW IN THIS YOUNG STELLAR SYSTEM.
