How to see deployed Starlink "Racetrack" flares

Rough Sitrec Permalink (without TLE) :

Since we get a few timelapses, I've added a "Simulation Speed" in the "Start Date/Time" folder. This is best adjusted on frame 0 (the time calculations are based around syncing to a video, but of course there's no video in the generic Night Sky sitch, but that's still how it works).

It's saves in the permalink, here's the updated one for the above with it set to 16 (a rough match)

Looks like there's several planes there. In theory you could drop in their KMLs. It's an excellent video.
Nice video of Starlink Flares here from the Centro Astronómico de Trevinca, in northwestern Spain:
Nice video. Should send it to Ryan Graves' organization, as it's coming from an astronomical center, and doesn't have the baggage of skepticism associated with it. Enough of these videos from observatories and he'll have to concede, although with the number of future launches, it's set to get much busier up there soon and I think the mystery will diminish.
A localish report, I looked in Stirec but did not see a train, perhaps the TLEs are not up to date enough if this was a recent launch?

They say "about 25 of them" in another reply

The time appears to be accurare to UTC-3 Time. It matches with sitrec exactly.

1. Please excuse my poor production.
2. @Mick West permalinks arent being generated.

A nice image and article about how to see starlink flares...

We’re back to the time of year when the predominance of Starlink satellites can be briefly illuminated low over the northern horizon as the sun approaches the Summer Solstice here in the mid-latitudes of the northern hemisphere. This predictable phenomenon is currently little known, and recognized only by the few who have directly observed it (and chosen not to attribute the ‘bright lights in the sky’ to UAP phenomena). This phenomenon of concentrated flaring has been occasionally reported by airline pilots who often have clear views at night from high altitudes in the polar directions (northwest to northeast in the northern hemisphere, etc.), which makes the satellites easier to observe; see the HeavensAbove diagram below for a graphical depiction of the illuminated satellites.


This image is particularly interesting, showing the western 'dusk' flares and eastern 'dawn' flares.
I first directly observed this last April while shooting night panoramas in San Juan County, UT, and described the phenomenon as ‘satellites flaring at their most-northerly orbits’, but am now adopting ‘satellite swarm’ as it seems more apt. If you know when and where to look this time of year this flaring is quite a sight, as the brighter flares that occur at ~8° above the horizon can reach magnitudes approaching -3! I routinely witness as many as 5 satellites within the limited field of view of typical binoculars, and the flaring generally occurs over about 30 seconds, with the brightest reflections occurring for as little as 5-8 seconds. There are two flare phases visually apparent prior to the summer solstice: 1) a ‘dusk flare’ that occurs in the northwest part of the sky (~10° in elevation) ~90 minutes prior to ‘astronomical midnight’ (e.g. when the sun is at its lowest point below the horizon) , and 2) a ‘dawn flare’ that occurs approximately 90 minutes after astronomical midnight and is observed in the northeast.

Putting those details into sitrec....

Not race track but close enough:

Finally got to see a train last Sat 5/11 at about 9 EST in N Florida.

Was out looking for the solar flare event and right as going back inside here they come from the N / NW. They had an awesome green hue and if I didn't know about it I would have freaked out.
