Now that TLEs are available for stage-2, can anybody work out quick&dirty ground visibility locations/times/directions for early revs, to seek out serendipitous visual sightings related to fuel dump and other post-insertion dynamic events.

SpaceX has a video up on their Youtube channel:

We'll be looking for TLEs from 12 objects:
  Falcon 9 stage 2, CASSIOPE, DANDE, two CUSATs, three POPACS spheres, and four POPACS deployer parts.
Eventually a thirteenth when DANDE jettisons its adapter on day 14.

I'm not clear when the two CUSats are intended to separate.

Thanks. I didn't know about the DANDE adapter (is there a paper or something that describes this?)
And I don't know when POPACS and CUSAT do their thing - was guessing POPACS separation happens shortly
after ejection but CUSAT is commanded at a later date.

In any case, we now have 20 objects cataloged, so I wonder if the extra ones  are debris associated with the second
stage restart problem.

And one of the passengers, DANDE, has TLE's and has seen spacecraft beacons.

I get a 328 x 1493 km x 80.97 deg orbit, close to the planned 324 x 1,500 km x 80 deg.  The biggest divergence is inclination.

Also, this doesn't match any of the currently cataloged objects - would be interested to know if this is actually based on LV telemetry or just a prelaunch estimate

Has anyone found a link to audio for the media teleconference that followed the launch today?

It's worth posting this video taken from the ground, as it shows the first stage firing in puffs shortly after stage separation - our first look at the first stage deceleration burns! (from 4:00 onwards)

I'm of the mind that those mystery puffs we are seeing in that video are not first stage related, but are rapidly expanding gas from the exhaust of the MVac on the second stage. Based on when the call over countdown net referenced the relight of the first stage engines, that happened much later than this.

Seems to be originating from the first stage  (lower right) as the second stage continues on to the upper left.

Reminds me of Shuttle ET venting. Look for " ET-Sep venting" in the L2 video section

Maybe sun light glinting off of the inner stage?

I notice F9 v1.1 staging is at about T+ 2:54. A few seconds before staging occurs flight control announces the rocket is at 61 km altitude, 45 km downrange and moving at 1.8 km/s. At about T+ 8:00 they announce "First stage is ... relighting at this time." Is the T+ 8:00 burn the supersonic retro burn or the landing burn? What is the time is the burn that wasn't announced?

Looks like the attempted second stage re-start was seen over Reunion Island, on the opposite side of the Earth from VAFB: http://wikkit.tumblr.com/post/62684205892/tracking-a-new-space-ufo / http://www.reddit.com/r/Astronomy/comments/1ne46k/saw_this_tonight_in_reunion_island_what_is_it/

 I wonder if the stage broke up while attempting that? (due to the very high number of objects found related to this launch by NORAD, currently at 20)

From the SpaceX broadcast this morning you can actually see the RCS system firing on S1 right after separation.

Using the latest TLEs for the 20 objects now in the catalog (A to T):
- perigee altitudes range from 235 km (F) to 444 km (M)
- apogee altitudes range from 1350 km (A) to 1590 km (S)
- inclinations range from 80.961 (A) to 81.035 (K)

EDIT: 1590 should read 1598

So that's confirmation that it disintegrated?
