B , V , and R observations of the Be/X-ray pulsar IGR J06074+2205 were taken in 2023–2024 covering times of expected X-ray outbursts. However, no coinciding optical outbursts were found. The overall optical brightness of the system faded in all 3 filters, with the least decline being in B and the greatest in R . This suggests that a cool disk was contributing less light to the system.
