Here is my estimate, based on a proxy from the November launch, i.e. assuming
insertion at similar orbital altitude of ~280 km:

STARLINK 2
1 70000U 20999A   20007.09677084 0.00069181  00000-0  15681-3 0    08
2 70000  53.0052 038.1027 0009048 332.8942  43.4811 15.96737629    03

Note that T.S. Kelso has made an estimated elset available based on a
SpaceX-provided State Vector:
