Original ITU filing for Tyvak-0130 had 37deg 500km orbit, but rideshare payloads adjust their orbits all the time to match flight opportunities.  It has UHF and S-band antennas.

Tyvak-0130 is described in a NOAA commercial remote sensing filing as “an optical spectrum astronomy observation satellite”… https://www.nesdis.noaa.gov/CRSRA/files/Tyvak-0130_NOAA_Summary.pdf

All Times Approximate

00:02:31   1st stage main engine cutoff (MECO)
00:02:35   1st and 2nd stages separate

01:38:10   Starlink satellites deploy


A bit different than usual

Seems like the second burn of S2 is 2 seconds longer than L27, maybe higher orbit for ride share payloads? Which can explain why there is only 52 satellites...

Yes, insertion orbit should be 569 km x 581 km

Is the LV erected yet at the pad?

SpaceX has raised a Falcon 9 rocket on pad 39A in Florida for launch with 54 satellites at 6:54pm EDT (2254 GMT).

There’s a 70% chance of good weather for launch at the Kennedy Space Center. SpaceX is also tracking weather in the booster landing area.

Still 70% GO, with moderate booster recovery risk
