Two perpendicular scans over the position of V1280 Sco were carried out with the RXTE PCA on Feb 21, 2007 between 18:54 UT and 19:27 UT. The data from detector 2 (which has the particle protection of a propane layer) give a 3 sigma upper limit contribution of V1280 Sco of 0.15 mCrab or 3.6x10^-12 ergs cm^-2 s^-1, 2-10 keV. Detectors 0 and 1 were also used during the observation. Preliminary analysis of detectors 0, 1, and 2 together gives a best fit of 0.12 mCrab, but only at a level of 2.4 sigma due to higher background variations.
