Hi All, Note that this is a pre-dawn launch window for southern California residents, and although the Delta IV is a (dimmer) liquid rocket, it has solid rocket strap-ons for the first stage which make the initial minute or two of flight much more visible. Unfortunately, once the SRBs burn out, there isn't much of a contrail to speak of -- just a moving bright dot. Here's a YouTube link to a video of a recent evening launch of a Delta IV out of Vandenberg: http://www.youtube.com/watch?v=hlc59JriHpM --Rob -----Original Message----- From: SeeSat-L-request@satobs.org [mailto:SeeSat-L-request@satobs.org] On Behalf Of Ted Molczan Sent: Thursday, November 02, 2006 11:49 AM To: SeeSat-L@satobs.org Subject: DMSP 17 search elements DMSP 17 is scheduled to be launched from VAFB on 2006 Nov 04, between 13:53-14:03 UTC.
