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