It is found that X-ray emission of 3U 0527-05, measured by the Astronomical Netherlands Satellite, comes from the direction of the Orion Nebula M42 ( NGC 1976). The mean flux at earth is 1.0 (plus or minus 4) x 10 to the -10th (1.3-7 keV) or 1.5 (plus or minus 0.3) x 10 to the -10th (1-8 keV) erg/sq cm and the corresponding intrinsic X-ray luminosity is about 3.8 (plus or minus 0.8) x 10 to the 33rd erg/s (1-8 keV), assuming a distance to the nebula of 460 pc and a hydrogen column density of less that 3 x 10 to the 21st atoms/sq cm. None of the candidate objects proposed earlier as a possible X-ray source - Theta(2) Ori A, Theta(1) Ori B BM Ori and Theta(1) Ori C - show clear evidence for emitting X-rays. The observed X-ray signal may be explained, however, as emission from coronas around T Tauri stars within the nebula.
