  We report the results of our observations of the nebular complex MH9/10/11,
associated with the ULX HoIX X-1, with scanning Fabry-Perot Interferometer. Two
regions differing by their kinematics and line ratios may be distinguished,
roughly corresponding to the bubble nebula MH9/10 and fainter HII-region MH11.
For MH9/10 we find the expansion rate of 20-70km/s that is different for the
approaching and receding parts. MH11 is characterised by very low velocity
dispersion (less than or about 15km/s) and nearly constant line-of-sight
velocities. Properties of MH11 may be explained by photoionization of gas with
hydrogen density of about 0.2cm^-3. Luminosity required for that should be of
the order of 10^39erg/s. Similar power source is required to explain the
expansion rate of MH9/10. Modelling results also indicate that oxygen abundance
in MH11 is about solar.
