  In this work we present the results of a search for continuous gravitational
waves from the Galactic Center using LIGO O2 data. The search uses the
Band-Sampled-Data directed search pipeline, which performs a semi-coherent
wide-parameter-space search, exploiting the robustness of the FrequencyHough
transform algorithm. The search targets signals emitted by isolated asymmetric
spinning neutron stars, located within 25-150 parsecs from the Galactic Center.
The frequencies covered in this search range between 10 and 710 Hz with a
spin-down range from $-1.8\times10^{-9}$ to $3.7\times10^{-11}$ Hz/s. No
continuous wave signal has been detected and upper limits on the gravitational
wave amplitude are presented. The most stringent upper limit at $95\%$
confidence level, for the Livingston detector, is $\sim 1.4 \times 10^{-25}$ at
frequencies near 160 Hz. To date, this is the most sensitive directed search
for continuous gravitational-wave signals from the Galactic Center and the
first search of this kind using the LIGO second observing run.
