Who took that picture? I would love a higher res copy for a background

The view from Exploration Tower at Port Canaveral of the SpaceX Falcon 9 launch to the International Space Station from Launch Complex 40 at Cape Canaveral Air Force Station at 1:52 a.m. Sunday morning Sept. 21, 2014. This is a two and a half minute time exposure of the launch. AP/Malcolm Denemark/Florida Today

I'd love to see a feed combination that shows separation vs LOX and SECO vs LOX. The LOX climbed in one direction meaning the second stage started tilting in the opposite. That tilt might be visible from outside.

New thread late tonight for RNDZ and Berthing updates.

Funnies with the TLEs.
The object cataloged as "Dragon CRS-4", 40210, was actually one of the solar array covers until just now and is in a rapidly decaying orbit like 40211.
40210 has now been swapped with 40212 (i.e. the latest TLEs for 40210 give the orbit of the object formerly known as 40212, and vice versa). This objectis in a 204 x 349 km orbit as of 1400 UTC today, and, contrary to expectations
for Dragon, does not appeared to have maneuvered:

  Sep 21 0548 UTC   Orbit 203 x 358 km x 51.6 deg  RA = 344 deg
  Sep 22 1357 UTC   Orbit 204 x 349 km x 51.6 deg  RA = 337 deg

although it is clearly dense and not rapidly decaying, the lack of maneuvers makes me think it might not be
Dragon either... there are usually independent orbital elements on NASA's SkyWatch page at
http://spaceflight.nasa.gov/realdata/sightings/SSapplications/Post/JavaSSOP/JavaSSOP.html but they don't seem to have
added the Dragon yet for this mission, so I'm not really sure what's going on.

Coverage now for people logged in as pre-warned.

Before this thread gets closed ... Chris B., you posted the above a few minutes before the launch.  I think you were warning people that if server load got too high you'd limit page views to people logged in, but it wasn't at all clear, and certainly would not have been to a newbie here, which is of course the key audience for those kinds of warnings.  So, a gentle suggestion that you be a little more clear next time.  If that IS what you meant :)

As always, thanks for the coverage!

Can this thread remain open until we hear about first stage recovery/debris etc?
Unless it's already too late for that...

While I didn't read this at the time, chrisC is right, if it's worth doing then worth making it clear.

Little things can make a big difference. A good experience will help people come back. :)

Wasn't there a small satellite on the second stage of this launch - could this be what is being tracked here?

Nope, no cubesats carried on board the rocket this time, and only SpinSat is on board the Dragon for deployment from the ISS.

NASA, SpaceX Share Data On Supersonic Retropropulsion

Quote
After multiple attempts, airborne NASA and U.S. Navy IR tracking cameras have captured a SpaceX Falcon 9 in flight as its first stage falls back toward Earth shortly after second-stage ignition and then reignites to lower the stage toward a propulsive “zero-velocity, zero-altitude” touchdown on the sea surface (see images).

Cool! Here is the image from the article, and the caption:
Quote
In this thermal imagery captured shortly after stage separation, the top of the SpaceX Falcon 9 first stage appears as a dim dot with a fading plume within the brighter upper-stage plume. In the inset, the restarted first-stage engines power the first stage as it performs a propulsive descent to Earth.

Video. Well powered reentry looks very violent from that perspective.

Important info from video.
First stage maneuvers itself out of second stage fire plume
First stage peak altitude 140km.
Burn starts at 70km, ends at 40km.

Yeah, that's very cool. No idea why they gave it to Aviation Week and held it from presser release.

At least they gave them only single picture.
