We report Very Large Array (VLA) D-configuration observations of recently discovered High Mass X-ray Binary IGR J00370+6122 = BD +60 73 (ATEL #281, #282, #285). Data taken by the VLA Summer Students on 9 July 2004, from 16:58 to 18:58 UT, show no detections at the frequencies listed below with the nominal flux densities measured at the position of BD +60 73.

  • 1.46 GHz: 0.34 +/- 0.23 mJy/beam
  • 4.86 GHz: 0.055 +/- 0.044 mJy/beam
  • 8.46 GHz: 0.081 +/- 0.033 mJy/beam
  • 22.46 GHz: 0.44 +/- 0.20 mJy/beam
  • Error bars are 1 sigma. At 1.46 and 4.86 GHz the field-of-view is large enough to cover the full INTEGRAL error circle (ATEL #281), and we see no sources in that region to the noise levels indicated. The raw data are publicly available via the NRAO Data Archive.
