We present the MUSE observations of UGC 6697, a giant (Mstar 10^{10} Msol)spiral galaxy infalling in the nearby cluster Abell 1367. During its highvelocity transit through the intracluster medium (ICM), the hydrodynamicalinteractions with the ICM produce a ~ 100 kpc tail of ionized gas that we mapwith a mosaic of five MUSE pointings up to 60 kpc from the galaxy. CGCG 97087N,a small companion that lies at few arcminutes in projection from UGC 6697, isalso suffering from the hydrodynamic action of the ICM of the cluster. Alongthe whole extent of the tail we detect diffuse H$\alpha$ emission and, to alesser extent, H$\beta$, [OIII]$\lambda5007$, and [OI]$\lambda6300$. Bycomparing the kinematics and distribution of gas and stars (as traced by theCaII triplet) for both galaxies, we separate the ionized gas, as traced by theH$\alpha$ line, in a component still bound to the galaxy and a component thatis stripped. We find that the "onboard" component shows low velocity dispersionand line ratios consistent with photoionization by hot stars. The stripped gasis more turbulent, with velocity dispersions up to > 100 km/s}, and is excitedby shocks as traced by high values of [OI]/H$\alpha$ and [NII]/H$\alpha$ ratio.In the tail of UGC 6697 we identify numerous bright compact knots with lineratios typical of HII regions. These are distributed along the only streams ofstripped gas retaining low velocity dispersions (< 35 km/s). Despite being inthe stripped gas, their physical properties do not differentiate from normalHII regions in galactic disks. We find evidence of a past fast encounterbetween the two galaxies in the form of a double tail emerging from CGCG 97087Nthat connects with UGC 6697. This encounter might have increased the efficiencyof the stripping process, leaving the stellar distribution and kinematicsunaltered.
