I employed opt+freq calculation for a molecule using B3LYP/6-31G set and found Ehomo=-0.20111 and Elumo=+0.00211. Is positive value of LUMO possible?

From HOMO-LUMO values, I found energy gap (Elumo - Ehomo) to be 0.20322, which seems to be fine and also homo is more stable than lumo. But I am confused if the value obtained for E(lumo) is...
