We present a measurement of the temperature-polarization angular cross powerspectrum, , of the Cosmic Microwave Background. The result is based on$\sim 200$ hours of data from 8 polarization sensitive bolometers operating at145 GHz during the 2003 flight of BOOMERANG. We detect a significant correlation in the $\ell$-range between 50 and 950 with a statisticalsignificance > 3.5 sigma. Contamination by polarized foreground emission andsystematic effects are negligible in comparison with statistical uncertainty.The spectrum is consistent with previous detections and with the "concordancemodel" that assumes adiabatic initial conditions. This is the first measurementof using bolometric detectors.
