  We present the results of an all-sky search for continuous gravitational wave
signals with frequencies in the 500-1700 Hz range targeting neutron stars with
ellipticity of 1e-8. The search is done on LIGO O2 data using the Falcon
analysis pipeline. The results presented here double the sensitivity over any
other result on the same data. The search is capable of detecting low
ellipticity sources up to 170 pc. We establish strict upper limits which hold
for worst-case signal parameters. We list outliers uncovered by the search,
including several which we cannot associate with any known instrumental cause.
