It's possible that the tug changes from a long tow (better out at sea) to a shorter one (better manoeuvrability)

hmm could that explain ElsbethIII's dance near landing zone ?

Carnival Fascination is getting in port, so we should be able to see if the ASDS leaves today

Re the recently constructed stand; this extract from the Draft CCAFS SLC-13 Environmental Impact Assesment gives some (official) sense of it's size, construction and purpose:

Quote
...a steel and concrete “stand” would be built to secure the Falcon stage during post-landing operations. The stand would consist of four Individual pedestal structures which would be transported to site and bolted to a concrete base. Each of the four pedestals, would weigh approximately 15,000 lbs, and would be 107 inches tall and 96.25 inches wide. A mobile crane would lift the stage from the landing pad, and transport and place it on the stand. Activities such as allowing the landing legs to be removed or folded back to the stage (flight position) prior to placing the stage in a horizontal position would occur there.

Here comes our spy ship. And one of the Mcallisters is doing rounds..

Just as Fascination passed under Dames Point bridge, an anomaly in air gap data was observed  ;D

http://tidesandcurrents.noaa.gov/ports/ports.html?id=8720376&mode=airgap

EDIT: Lot of activity on deck. Erin Mcallister is nearby!(For cruise ship probably)
EDIT2: Ooh people are checking stuff on deck! Group of three inspecting specific points on deck(grid formation) one by one.
Edit3: added video

Is the cruise ship being used by the SpaceX people? Seems so odd that it parks right next to the drone ship so regularly. :)

Unless it's doing regular rounds or trips and they just happen to coincide. Thanks for the video Ohsin.

The cruise ship is a cruise ship.
It sells inexpensive short-term cruises round the Bahamas.
You can probably get a closeish in-person look at the barge .

http://www.carnival.co.uk/BookingEngine/cruise-search/?shipCode=FS&CID=Psearch_Brand_Ship_Names_Classes0000524&gclid=CIyi-ZjHhMMCFeHHtAodORAA5g
The next available trip is a 5 day cruise to the Bahamas leaving on the 17th, for about $600.

Upcoming F9 launches are in a couple of days, the 29th, and Feb 17th.
Assuming the barge is returned to port within a couple of days, if you wanted to have a chance of seeing it, you'd probably want to be either departing or arriving on 31st Jan/1st Feb, or Feb 19/20.
I don't off-hand know if the Carnival Fascination goes faster in the river than the barge.
If so - that would be an additional opportunity to catch it.

There is a 5 days cruise departing on the 26th, and arriving back on the 31st with interior cabins for two at $350.
And one departing on Feb 14th, and arriving the 19th.

(I am not connected in any way with the above cruise-line)

Re the recently constructed stand; this extract from the Draft CCAFS SLC-13 Environmental Impact Assesment gives some (official) sense of it's size, construction and purpose:
From the same source (there's a dedicated thread), the following bit gives some insight into ASDS on-board operations:
Quote
A FireX system would be constructed with three or four remote controlled water cannons mounted on posts above ground to allow for remote firefighting capabilities. [...]

[...] Safing activities would begin upon completion of all landing activities and engine shutdown. The LOX oxidizer system would be purged, and any excess fuel would be drained into a suitable truck mounted container or tanker. Any remaining pressurants (i.e., helium or nitrogen) would be vented, and any FTS explosives would also be rendered “inert” prior to declaring the vehicle safe. [ed: then presumably the stage would be secured and the ASDS would return to shore and the following steps would take place at port:] The vehicle would then be lifted and placed on to the stand; the landing legs would then be removed or folded back into place. The vehicle would then be lowered into a horizontal position, placed on a transport vehicle and taken to a SpaceX facility.

Looks like the last unidentified yellow 'box' on ASDS is also a fuel tank...so five NOV fuel tanks and two NOV generators.

Can't have a gangway attached if it's going to leave...

So yes, that would be my guess

I was thinking may be they'll attach from other wing...it is facing other way today you see.

Isn't it a bit soon for it to leave if it is going to be used Saturday? Maybe it is going somewhere else

Oh, look at the ramps in the water to access the underside of the overhangs. I hadn't seen that before.

So perhaps they are spinning the barge 180 degrees to get to the underside.

As it left a small boat was lowered by crane to follow it.
