We report additional observations of the suggested afterglow counterpart of Fermi Trigger 430583595 (see Atel 6416), obtained using the 1 m "Omicron" telescope at the Observatoire de la Cote D'Azur. Our observations were obtained on August 26.1 and 28.1, some 1.4 and 3.4 days respectively after those reported in Atel 6416. The proposed optical counterpart is still present in our whitelight images, at a magnitude comparable to that reported in Atel 6416. Hence there has been no obvious decay of the counterpart on this timescale, suggesting it is unlikely to be the counterpart of the Fermi trigger.
