Comments: Imaged Jupiter and Io May 30th in quite ordinary seeing, that said have resolved some measurable detail. I note a small red oval in the NNTeB midway between the F limb and CM. A large bright oval in the NTB midway between the F limb and CM. At least two red barges are resolved in the NEB. The scalloped Southern edge of the SEB is relatively well resolved and Oval BA is well seen with a cluster of bright ovals below it.
