Hi Bjorn,

You'll probably have already seen that your observations match the two
elsets of Object D [43218/18020D] best. JSpOC has published only two
elsets for object D:

Epoch:                       Orbit:
18053.65423199 (15:42:06UT)  495km x 516km _at_ 97.46 deg
18053.65952442 (15:49:43UT)  211km x 517km _at_ 97.27 deg

This confirms that object D is indeed the Falcon 9 R/B of which you an
others have observed either the fuel dump or the de-orbit burn. Given
that the Broadcast Warning de-orbit area is located at latitudes of 33
to 50 degrees in the Pacific, the most efficient de-orbit burn
would've been half an orbit earlier, indicating you observed the fuel
dump. However, it is also possible that the upperstage had surplus
performance to de-orbit later.
