We present the results of a photometric campaign of the dwarf nova V1040 Cen. The light curve shows two normal outbursts with recurrence time ~ 40 days and amplitude ~ 2.5 mag. Quiescence data show oscillations with periods in the range ~ 0.1 days (2.4 h) to ~ 0.5 days (12 h) of unknown origin. We measured the orbital period of V1040 Cen to be P_orb=0.060458(80) days (1.451 ±0.002 h). Based on the M_v-P_orb relation we found the distance of V1040 Cen to be 88 ±31 pc. In this paper we also report the detection of eleven new variable stars in the field of the monitored dwarf nova.
