Do we have any idea how long SpaceX will need to switch 39A back and forth between F9 and FH as it currently stands?...  ???

DM-1 in early Nov and STP-2 in late Nov seems a possibility...  :-\

I believe I read it took 2 days to convert 39A from FH to F9 capability after the demo flight.

the launch schedule thread says this launch is now early December, what's the source for that ?

To what “launch schedule thread” are you referring?

This is probably a misread of the "FPIP chart" made by smoliarm as that wasn't meant to be accurate.

Ah
We are, as they say, “in violent agreement”.
With SpaceX DM-1 said to have to wait until November, it is a reasonable assumption that STP-2 will slip into December.
But that’s all it is, a reasonable assumption. 
Let’s hope for an announcement soon.

Given DM- is big held up by other schedules, couldn't STP-2 move to the left and go first?

Because I imagine the former is a higher priority for Space X than the latter.

If STP-2 was able to move left then it probably wouldn't have moved right in the first place.

Depends whether we're talking absolute left and right (i.e. calendar dates) or just relative left and right (i.e. order of missions). STP-2 probably can't move very far to the left in absolute terms, but it could conceivably stay at the same NET date whilst the DM slips rightwards past it due to ISS scheduling constraints.

Taipei, Aug. 3 (CNA) The FormoSat-7 satellite group, a U.S.-Taiwan collaboration that could be launched by the end of this year, will greatly improve the world's typhoon prediction capabilities, the deputy head of the Central Weather Bureau said Friday.

While Lai said that Formosat-7 would be delivered to the US at the end of next month, agency officials appeared more reserved about its launch schedule, which has been postponed several times.
The satellite cluster will most likely be launched next year, Lin said, adding that the actual date has yet to be determined.
As Formosat-7’s launch is managed by the US Air Force and US company SpaceX, the NSPO can only wait for notification two months prior to launch, he said.

LightSail 2 updates: Launch date slips, environmental test complete, new video released

The Planetary Society's LightSail 2 spacecraft has proved it can withstand the rigors of launch aboard SpaceX's Falcon Heavy, the powerhouse rocket that will carry it into orbit. But that ride to space won't happen until at least November 30, as SpaceX works through a list of other payloads in line to fly first.

Pretty sure that was sourced based on this forum post. I could be wrong though.

Sorry, just saw this. Comga's comment cued me to ask a friend and they corroborated with "Q1/Q2". No reason to question Comga's NET, as such.

This is surprising.  STP-2 is not an EELV launch so I guess it's a good time for USAF to give it a try.

Fox said the mission [STP-2] will launch on the second of two back-to-back launches of SpaceX’s Falcon Heavy rocket, after the launch of the Arabsat-6A spacecraft. “It will launch after the successful launch of Arabsat, which is currently manifested for March,” she said.

The two launches, she said, will use the same set of first stage booster cores. “They will recover and reuse the boosters,” she said, with the second launch taking place about a month after the first.

Does this mean just the two side cores, or maybe also the center core?
The way it reads to me seems a bit ambiguous. And maybe it's just me.

It seemed ambiguous to me as well. If they had said "side and center cores" it might have been clearer. Maybe they are still not sure they can stick the center core landing and have a second center core in production just in case? This wording gives them wiggle room.

I really have no idea what this mission looks like now as far as the orbits it will go through.  Originally it was 720km x 720km x 24deg for the first deployment and then went to 6000 x 12000 x 45deg for the second deployment.  Cosmic-2 sats were then supposed to use their own propulsion to lower their orbits to 520 x 520 x 24deg.

At some point a 300 x 860 x 28.5 orbit seems to have been added so that some of the secondary payloads without propulsion would deorbit in a reasonable amount of time.  Cosmic-2 also doesn't necessarily need to be at 24deg, they could probably use 28.5deg

In their FCC permit filing (0338-EX-ST-2018), LightSail team said they didn't want to go below 720km because drag would overcome the solar pressure on the sail.  A failure to deploy the sail would result in it taking about 90 years to deorbit from that altitude.

I think I stumble over the answer by accident.  Side boosters and center cores will be recovered (at least that the intent) of Arabsat 6A, then refurbish the in 60 days and fly SAF’s Space Test Program 2 (STP-2) with them.

Taiwan saying Q2 for this launch with Formosat satellites to be transported soon (February) to US:

Taiwanese satellites soon to head for launch from Florida
Formosat-7 satellites will enter space atop SpaceX’s Falcon Heavy rockets
By Asia Times staff January 7, 2019 6:46 PM (UTC+8)

Taiwanese authorities say the island’s new Formosat satellites will soon be transported to the US by China Airlines, the island’s flag carrier. This could happen after the Lunar New Year break in February, with the satellites then being launched into service aboard SpaceX’s Falcon Heavy rocket from Kennedy Space Center in Florida in the second quarter of 2019.
