  In course of the MUCHFUSS project we found two new HW Virginis systems.
J192059+372220 (J1920) has an orbital period of 0.169 d and an M dwarf
companion with a mass of $0.116 M_{\odot}$. J162256+473051 (J1622) has the
shortest period (0.069 d) of all known HW Virginis systems. Its companion has a
mass of $0.0635\pm 0.004 M_{\odot}$ and is therefore the second close brown
dwarf found orbiting a subdwarf B star.
