Possible first stages for Starlink 4-11: 1051.12 or 1063.4.

1063.4 landed on last Nov. 24.  1051.12 landed last Dec. 18.

1071.2 would probably not yet be available, and it is being held for NROL-85.

No other completed and tested first stages are known to be in California.

Static Fire or no Static Fire before launch?  My guess:
Probably yes if 1051.12.  No if 1063.4.

Edit Feb 21: It's 1063.4.  1051.12 returning to Florida.

B1060.11 for Starlink 4-9.

OCISLY has departed Long Beach!

Tug Scorpius will tow it ~640 km downrange. GO Quest will join for droneship support whilst NRC Quest recovers the fairing halves.

No, but my guess would be 49 (because that's 3 less than the 52 satellites launched on 4-4). Assuming they're sticking to the new higher deployment altitude.

One thing confusing to me you lose 2 sats to vandy and 3 sats to Florida launch for 2 burn orbit insertion. Why this difference any reason

Orbit is slightly lower than for the 4-8 mission, that might contribute

The dogleg maneuver required to get into a 53.2 degree orbit from SLC-4E requires less dV than the dogleg maneuver recent Cape Starlink missions like Starlink 4-8 preformed.
