SpaceX to launch 60 Satellites in one go

Yet another launch delay brings it to a launch at 1406UTC today, 29 January, though SpaceX have issued a hazardous operations NOTAM for tomorrow as well so perhaps they aren't entirely confident it'll leap off the pad today.

Left the pad on time to the targeted orbit. First stage returned to an oceanic landing and one half of the fairing was caught (the other half soft landed in the Atlantic and is being fished out). The Starlink satellites have been deployed.

Astronomers are still trying to work with SpaceX to reduce visual and radio visibility.

Plenty of examples of interference up thread. Here interference in radio meteor observations:

Leading satellite mega-constellation companies SpaceX and OneWeb have met with astronomers in Europe to discuss the impact their operations could have on observations of the Universe.

There's concern that the size and brightness of the firms' planned fleets could interfere with the work of professional telescopes.

The parties discussed the issues in a private meeting at the Royal Astronomical Society in London, UK.
Hope there is a way for the two parties to co-exist.

And tomorrow, from Baikonur at 2142UTC on a Soyuz, the first operational tranche (34 out of an eventual 650) of OneWeb low latency communications satellites head to a polar orbit.

Comfortable chair.
Think I saw some today.
Was just before 6am.
Saw five or six in a line, same speed, equidistant. In Kent.

The next clutch are targeting 1546 UTC this Saturday 15 Feb.. No initial good visibility for the UK - there is one marginal pass on the second orbit at 1740UTC low in the SW but since the weather is going to be atrocious...

Most likely it was them. There was a pass at 0558UTC - the most recent set have pre-dawn passes for our (UK) latitudes right now.

e2a: This time the deploy is going to be much earlier - 15 minutes post launch over the Atlantic rather than about 45 minutes near Australia.

2e2a: ~24hr delay for this Starlink launch due to weather now being flagged up.

The IAU have published some commentary on the subject of satellite megaconstellations interfering with astronomical observations, including some details of ongoing discussions with SpaceX.

Next Starlink launch pushed to Monday 17 Feb 15:05:55 UTC. No decent visibility for the UK on launch or subsequent days.
