Hi Will,
Recent video from this station has been cited in some places on the internet as being evidence in favour of the existence of Nibiru (not that particular object you are referring to though).
See here for one:

The person who comments on the video at this site is quite obviously a jibbering idiot of the highest order (without putting too fine a point on it).
I really don't know what the object you are referring to is. It is not a "star" but if it isn't an artefact in the image, I'd say it is a reflection of light from the station of some sort, on something that is holding up the antenna pole or attached to the top, but it too small to be shown by the camera itself unless illuminated.
There is a streak of light from the station that points virtually at that pole so light is heading that way. The obvious conclusion in the absence of evidence to the contrary is a probable reflection or a hot pixel or something mundane. It is in many frames of the video at this site at exactly the same spot.
It has no diurnal motion like the fixed stars so it is not a star, planet or other distant object that would be made to appear to move by Earth's rotation. The Earth's rotation would show diurnal motion were it so. So if real, it is close at hand (ie less than a few Km distant, if not a couple of hundred metres.
Best,
Les D
P.S Same guy maintaining the site above also makes excellent videos of lens flares and internal reflections of the Moon showing what he purports to be Nibiru:

Laugh-a-minute stuff!
