  We have performed a long-term measurement of the neutron flux with the High
Efficiency Neutron Spectrometry Array HENSA in the Hall A of the Canfranc
Underground Laboratory. The Hall A measurement campaign lasted from October
2019 to March 2021, demonstrating an excellent stability of the HENSA setup.
Preliminary results on the neutron flux from this campaign are presented for
the first time. In Phase 1 (113 live days) a total neutron flux of 1.66(2)
$\times$10$^{-5}$ cm$^{-2}$ s$^{-1}$ is obtained. Our results are in good
agreement with those from our previous shorter measurement where a reduced
experimental setup was employed.
