In this letter we report on a numerical investigation of the Aoki phase in the case of finite temperature which continues our former study at zero temperature. We have performed simulations with Wilson fermions at β=4.6 using lattices with temporal extension Nτ=4. In contrast to the zero temperature case, the existence of an Aoki phase can be confirmed for a small range in κ at β=4.6, however, shifted slightly to lower κ. Despite fine-tuning κ we could not separate the thermal transition line from the Aoki phase.
