L-1 Day Planning Forecast
Western Range Operation Forecast
W7510
Issued: 21 Dec 17 / 0600L (1400Z)
Valid: 22 Dec 17 / 1727L (23/0127Z)
Vehicle/Payload: Falcon 9/Iridium-4
Location: VAFB SLC-4
T-0 Forecast: High pressure continues to build into the western CONUS in the wake of yesterday’s cold frontal passage. The impact will be relatively dry northwesterly flow aloft, light surface winds with the loose pressure gradient and no marine layer clouds. Surface winds will be out of the northwest through north from 320-350 at 8-12 knots for T-0. Temperatures will range from 55-60F at T-0. Upper-level winds will be out of the northwest from 330 at 80 knots between 38,000 to 41,000 feet. And finally, the space weather indices for proton and x-ray flux are currently reading at background levels. The overall POV will be 0% with no areas of concern.
24 Hour Scrub Forecast: A weak upper level trough of low pressure will move into central California which will bring an increase in high-level clouds; otherwise, expect similar conditions as the primary day. Surface winds will be out of the northwest through north from 320-350 at 8-12 knots for T-0. Temperatures will increase slightly at 57-62F while max upper-level winds will decrease, remaining out of the northwest from 300 at 60 knots from 38,000 to 41,000 feet. The overall POV will be 0% with no areas of concern.
Significant Clouds:
Cirrus
Coverage
1/8 ths
Bases
28,000 ft
Tops
29,000 ft
Visibility: 7 Miles
Weather: None
Wind: 320 - 350 at 8 - 12 knots
Temperature: 55 - 60° F
Overall probability of violating weather constraints: 0%
Area of concern: None
Overall probability of violating weather constraints for 24 Hour Delay: 0%
Area of concern: None

I took this during last night's pad visit - they have better lights now at pad. We went vertical about 8pm, and everything looks good for tonight's launch. While no landing, I'm told there should still be some good video on the way down to "water landing". #GoIridium-4!

Update, no video on the way downQuote
My bad. I was wrong about the video, there will NOT be video from the first stage on the way down - focus will be on the second stage through to satellite deployment (MY favorite part...). Sorry to get you all excited about some sort of “splash cam”. Probably too dark anyway!

Something a little new this time with airspace restrictions for this launch. There is a TFR posted downrange from the launch as an extension to the active warning area (W-537). This hasn't been the case with any of the earlier Iridium launches this year. I'll ask the question over on the discussion thread, but is there any difference in launch azimuth this time around?

Apparently a slight azimuth offset as compared with flight 3 -
