It sure was cold waiting out there at the cruise terminals waiting for them to light the fuze.  Beautiful launch, though.

Did you take any photos of the launch last night?

BIG NOD  :)

THANK YOU PAT CORKERY!

Wow. Love those mach diamonds.
Question: Would that be an injector issue with the right engine? Running a little lean or rich perhaps? Just slightly brighter in the exhaust plume than the other two engines.

Any news on whether spacecraft separation has occurred?

It seemed to take forever for the D IV-heavy to clear the tower this time... Are there any examples of rockets which clear the tower any slower? The Shuttle seems to jump off the pad in comparison...

Saturn V

Absolutely, Jim...the one Saturn 5 launch I was lucky enough to witness (Apollo 15) was from south of the complex by CCAFS Gate 1.
I remember very clearly how long it took to actually clear the exhaust plume that obstructed the vehicle upon ignition.

No, my little point-and-shoot wouldn't focus on the rocket.  next time, I hope to get some good pics with my new camera, especially if I can figure out how to connect it to my 100mm, 60x, spotting scope.  I'm going to work on that at this week's birding festival at Titusville BCC campus (when I'm not working with the panthers, alligators, snakes, etc.).

Just a little streaking by the ablative nozzle

Not sure if you've seen these but Ben got some really good shots of the launch:

Saw this launch with psloss and SEDS-UCF and a whole bunch of other people from Kars Park about 7-miles from the pad. It was every bit worth the three delays and cold temperatures. The sound was INCREDIBLE. Almost indescribable. I'm working on getting some pics available from the video I took, which ended up being a little better that I thought it would be given the auto-focus of my camera.

I like this one:

http://www.launchphotography.com/Delta_4-Heavy_NRO_L-26_10.JPG

I remember when I first saw that timelapse (dunno if that's the correct term, or is it over exposure? - anyway) type of photo with a shuttle launch in the 80s and it was the first time I realized (as a kid) that they didn't "go straight up" ;D

long exposure or time lapse; definitely not overexposure.

It's a beauty of a shot. :) Nice arc.

None, and I'm wondering if there will be any official statements to that effect. 

There is this today - a press release from PWR. 

http://sev.prnewswire.com/aerospace-defense/20090118/NESU00218012009-1.html

It says that "The upper-stage RL10B-2 helped place the satellite into orbit."  I suspect that PWR wouldn't have issued this if something had gone wrong with the RS-68 or RL10B-2 engines on this flight.

The release also states that "This was the 716th launch of a Delta vehicle under Pratt & Whitney Rocketdyne's power."  Not strictly correct, of course, (there have only been 328 Thor-based Delta and 9 Delta IV launches) but it was the 716th flight of a Thor IRBM, Thor SLV, Thor-derived Delta, Thor-derived NASDA "N" or "H-1", or Delta IV. 

ULA is saying that it will not provide any further updates beyond the "successful liftoff" notice.

Is the jiggle (about even with that blue star trail) wind shear, strap-on jettison or ground jiggle?
If I like something on NSF, it's probably because I know it to be accurate.  Every once in a while, it's just something I agree with.  Facts generally receive the former.

as long as the culture doesn't become Titan-ic between now and then.
"Titanic culture"?  What's that saying about "Glass Houses?"  ;)[/quote]

Touché.  I'm doing what I can, and Tuesday will be a new day at 3rd and E SW.

I'm guessing tripod vibrating due to wind or rocket rumble.

Would they release information if there had been a problem? The lack of any negative updates would suggest all went to plan. Understand why the Americans don't release details, glad we got the coverage we were allowed.
