It did send some data right after the first SSTV transmission that was not the usual telemetry. Did anyone catch what that was?

Thanks to @pu4elt for the heads-up I managed to grab this on the 093xZ pass over UK; actually same image a couple of times but this best of them. I think this was the only viable pass over UK during the activation period so glad to catch it.
