Sat-based maritime tracking co @exactEarth: 4 of 10 @IridiumComm sats launched Jan. 14 carry our exactView™ RT powered by Harris payloads.
Quote from: edkyle99 on 01/16/2017 02:32 pmI've also been wondering about the orbit. Some pre-launch discussion described a planned 667 km insertion orbit. The tracked orbit was more like 620 km.Iridium CEO tweeted before the launch (couple weeks ago?) that the parking orbit was 625km.

The initial insertion orbit for Iridium second-generationsatellites is a 625 km altitude circular orbit with an inclination of 86.66 degrees.
And from their FCC application: https://apps.fcc.gov/edocs_public/attachmatch/DA-16-875A1.pdf
Iridium proposes to replace its existing constellation with a new constellation using the same orbital parameters, providing the same global coverage, and transmitting on the same frequency bands. Like Iridium’s first-generation satellites, the new satellites will be capable of operating in the entire 1616-1626.5 MHz band; however, Iridium here requests no change from the operating frequencies specified for its first-generation satellites. To provide continuous service during the transition, Iridium proposes to replace its existing satellites one-for-one with new satellites as they are launched.
The crowd noise is heard at 22:58 of the hosted webcast 03:19 mission elapsed time just after they cut away from the inside the fairing shot.

...Desch said the 10 satellites launched on Jan. 14 will be sent into Iridium’s plane 6. Eight will stay there; the two others will be drifted over to Plane 5.That will fill the most glaring hole in Iridium’s coverage. “For our next launch, in April, we’ll launch into Plane 3 — that’s the other hole,” Desch said. “Every launch provides resilience and redundancy to the existing network.”...“The way I look at it, even if they only get 10 launches off I think I have a good shot at getting my five” because of the less-crowded manifest at Vandenberg, Desch said. “We have 20 or more satellites in the factory and ready — enough for two launches. We are really only gated now by the rockets.”...
Satellite dispenser?

Quote from: Space Ghost 1962 on 01/15/2017 11:03 pmTo reiterate, SX is losing customer payloads for no good reasons. They can innovate and use agile - that's fine. But to do so w/o the unacceptable LOM means you have to do far better than they are doing.And I'm certain Musk himself would agree with me on this point. Ask him.Emphasis mine (this time)Practically every customer payload ever lost (no matter who the launch service provider was/is) was lost for no good reason.

SpaceX may be doing Agile but everyone has lost customer payloads for no good reasons.
It's more like a collective murmur. Perhaps their on-board view also cut off at that time. Agree after this discussion that there is no issue with the orbit or any certain indication of a fairing separation problem. I think the crowd reaction would have been more substantive if, say, a fairing half had hung on for too long! - Ed Kyle
I haven't watched all the launches, but I don't remember ever seeing the view of the fairing separation from the view of the second stage. When I've seen the separation (as far as I can remember), it is usually from ground or first stage cameras.

Falcon 9 S2 can hardly last a couple hours.Right, if the 11th object is real, and is stage 2, then the window for relight has long since passed and it will be up there in orbit for many many years to come. If its not the stage then I have no idea what it could be. If it was in fact a failed relight of the second stage, I wonder how that affects SpaceX operations for the next flights.
