  This work presents the magnetic field geometry in a complex of three cometary
(with head-tail morphology) globules, namely LDN 323, LDN 328, and LDN 331,
using R-band polarization measurements of background stars. These observations
were combined with a Planck sky survey to study the large-scale morphology of
the magnetic fields in the region. The distances of the target stars were
adopted from the Gaia catalog. The variation of degree of polarization and
polarization position angle with distances of stars is analyzed. The field
geometry is mostly found to follow the cometary shape of the cloud, with some
randomness at certain locations. For studying the correlation between cloud
morphology and magnetic field orientations, a modified version of the Histogram
of Relative Orientation analysis was employed.
