  We report the results from observations of 24 gamma ray burst (GRB) fields
from 2005 and 2006 undertaken at the Danish 1.54m telescope at ESO/La Silla.
Photometry and positions for two previously unpublished host galaxy candidates
(GRBs 050915 and 051021) are presented, as well as for eight other detected
objects which are either known GRB hosts or candidate hosts. The candidates are
suitable for spectroscopic follow-up in order to have their redshifts and other
physical characteristics determined. In the cases where no likely host
candidate is detected inside the refined Swift XRT error circle we are still
able to put interesting and rather deep limits on the host magnitude. Based on
our detections and upper limits we have performed simulations which suggest
that the host galaxies are drawn from a fainter sample than previous (i.e.
pre-Swift) studies.
