Fully vertical just after 10pm ET.

No payload fairing. This should mean a Static Fire, followed by a return to the HIF for payload integration.

Also, no gray band on the second stage, so no extended mission for the second stage.

Static fire expected today around 17:00 UTC:

SpaceX is planning to test fire a Falcon Heavy at launch pad 39A at the Kennedy Space Center on Sunday. Ignition and a short burn of the 27 Merlin first stage engines is expected around midday (approx. 1700 UTC). The static fire test comes a week ahead of the planned launch of the U.S. military's secretive X-37B spaceplane.

Frost lines and condensation visible around the side boosters, so fueling for static fire is underway!

T-22 minute vent. (Yes, it's 22 for FH, 20 for F9)

STATIC FIRE! Falcon Heavy fires up at 39A ahead of USSF-52.

Does this mean we can assume launch December 7th local time and December 8th UTC?

Yep. Evening launch local time, will be on the 8th in UTC. It'll be more clear once the launch window is announced.

Post-static fire rollback in progress. Image grabbed from SFN feed. Time to mount the payload!

Initial orbit to ~48.25°:

Navigational Warnings have appeared which I believe are for the USSF-52 #OTV7 X-37B mission.
They point to (initial) launch into a 48.25 degree inclined orbit.
Map depicts 185 km parking orbit variant and direct 185 x 35188 Km insertion variant

There is a possibility that at soime point it makes a dogleg into a ~64 degree HEO orbit

Mission to GEO, after all.
Or a NOSS/Molniya HEO.
Well, well.

No, GSO is 0 degree inclination. Any other inclination is not "stationary"

gso is geosyncrinous ourbit not geostationary orbit! geo (geostationary orbit) is zero degrees GSO is not

Acronyms:

geosynchronous orbit (sometimes abbreviated GSO)

geostationary orbit, also referred to as a geosynchronous equatorial orbit (GEO)

parking plus insertion...

Do we know if the X-37 is rated for a GTO reentry?

Otherwise, this perhaps suggests X-37 with SM released in parking orbit, secondary payload behind SM still attached to the second stage gets boosted by second stage to GTO?

Just want to point out, it can do aerobraking as gradually as it likes down to LEO energy. It doesn't need to go from GTO to landing all at once.
