Abstract
We present deep WSRT 1.4 GHz observations of the Hubble Deep Field region. At the 5 sigma level, the WSRT clearly detects 85 regions of radio emission in a 10' x 10' field centred on the HDF Eight of these regions fall within the HDF itself, four of these are sources that have not previously been de tected at 1.4 GHz, although two of these are VLA detections at 8.5 GHz. The two new radio sources detected by the WSRT are identified with relatively bright (I < 21(m)) moderate redshift spiral and irregular type galaxies. In the full field, the WSRT detects 22 regions of emission that were not prev iously detected by the VLA at 1.4 GHz. At least two of these are associated with nearby, extended star-forming galaxies.
