I bet the Italians are happy 
Happier than aborting two minutes later.
True...point taken...just got caught up in wanting to see this finally go. I'd rather wait a while for a successful launch then have one go early and fail.

OOps, SCRUB
again?? 
Can see a cell phone go flying soon...lol
Hey, I threw it against a wall about 3 min before launch....wasn't connecting to anything...lol...AGHHHHHH!!!!!!!!! Another SCRUB!!!! Man when the phone finally kicked in and I saw VAFB's twitter say "1 min until launch" I turned it off and put it in my pocket, getting ready to see it. My heart was beating in anticipation!!! After a few minutes and nothing, I knew something was wrong. Then I checked the phone (again) saw a see of tweets: SCRUB...Man, it was so close....
Interested in the cause this time. Thanks for the updates everyone.

Delta II COSMO-SkyMed 4 Mission Rescheduled for Nov. 4
Vandenberg AFB, Calif., (Nov. 2, 2010) - The launch of Delta II COSMO-SkyMed 4 (Constellation of Small Satellites for Mediterranean basin Observation) mission is rescheduled for Thursday, Nov. 4 with a launch time of 7:20 p.m. PDT. During the terminal launch countdown on Tuesday, at approximately one minute before launch, mission managers noted a low second stage battery voltage reading. This battery is used to power the electrical systems on the Delta II second stage during flight.
To allow for crew rest after three straight days of launch attempts and engineers the time required to correct this issue, the next launch attempt is scheduled for Nov. 4. Updates to the COSMO SkyMed-4 mission status will be issued as new information becomes available. United Launch Alliance provides the Delta II launch vehicle and mission services under a commercial launch service contract administered by Boeing Launch Services for Thales Alenia Space-Italia (TAS-I

Wont't this conflict with the STS-133 launch attempt?

It shouldn't. There's a forty-degree difference in inclination and VAFB is four-fifths of an orbit away from KSC, if nothing else. I also suspect that the target altitudes will be different too.

Delta II COSMO-SkyMed 4 Mission Rescheduled for Nov. 5
Vandenberg AFB, Calif., (Nov. 3, 2010) - The launch of the Delta II COSMO-SkyMed 4 (Constellation of four SAR radar satellites for global Earth Observation performed for the Italian Space Agency, the Minister of Defence and the Ministry of Research) mission has been rescheduled for Friday, Nov. 5 with a launch time of 7:20 p.m. PDT. During a review and analysis by Thales Alenia Space of the current position of the three COSMO-SkyMed satellites currently on orbit, it was determined that in order for COSMO SkyMed-4 to be correctly inserted into the constellation, a launch could not take place on Nov. 4 due technical reasons.
The Delta II second stage low voltage battery issue has been resolved and the rocket is ready for launch. Updates to the COSMO SkyMed-4 mission status will be issued as new information becomes available. United Launch Alliance provides the Delta II launch vehicle and mission services under a commercial launch service contract administered by Boeing Launch Services for Thales Alenia Space-Italia (TAS-I).

I may have missed this somewhere, but does anybody know what the upper level wind limits are for this thing? According to the local meteorologists, starting this weekend we're supposed to have some changing weather, and I was just curious as to what the launch constraints are.

Winds aloft aren't absolute limits. It has to do with wind shear (dv/dh) and its effect on controllability. That's what the balloon releases are for. Theoretically also, if it were flying into a mean headwind it could underperform, but that's supposed to be within the 3sigma performance reserve.

ULA note they are still on for tonight. Let's see if we can get one vehicle off the ground today.
And they are back to a nominal webcast setup.
