  Anomalies of the cosmic microwave background (CMB) maps have been widely
acquainted nowadays from the Wilkinson Microwave Anisotropy Probe (WMAP)
satellite to the Planck satellite. One of the anomalies is a multipole
alignment from $l=2$ to $l=5$. In our work, we investigate the angular
distribution of gamma-ray bursts (GRBs) to find whether there is the same
anomaly of GRB as CMB. We perform spherical harmonics expansion on GRB samples
to derive coefficients of a few first terms of the expansion terms and find
that there is rough multipole alignment from $l=2$ to $l=4$ while the dipole
and $l=5$ multipole is in a distant direction, and that the quadrupole is
obviously planar and the other ones are normal.
