Isn’t that bigger news than it sounds at first? Part of the problem of finding planet nine must be knowing where it currently is on its orbit. A few possible observations should help to narrow down the space in which to look for it by a lot (rather: would make it almost clear where it currently is). Maybe JWST could be of help with testing the hypothesis that these early infrared observations of a moving object were of planet nine - once it has finally and savely launched and begun its operations?
