Greg's Nov 19th imagery of my geostationary UNID (UNK121118)

The imagery above is posted with kind permission of Greg Roberts (CoSaTrak, South Africa). It depicts the same geosynchronous UNID that I imaged from the Netherlands on the 18th, in an image Greg shot from South Africa on the 19th.

This object does not match with anything in USSTRATCOM's current satellite catalogue, or in our classified satellite catalogue. It probably is a commercial satellite that very recently has been relocated to this spot: if so, USSTRATCOM seems not yet aware of it.We have not been able yet to identify which satellite it could be.

For my November 18 discovery imagery of this object, click here.

As the object moves in an orbit with an inclination of 8.1 degrees, it makes a small daily "up and down wobble" perpendicular to the celestial equator (many geosynchronous objects do that). This is the reason it is showing a small trail in this 40-second exposure.

(the nearby object marked EUTE 48A in the imagery is the commercial geostationary satellite Eutelsat 48A)
