Is it too much to ask for a minor dip in Solar activity?? Just 7 hours later, at 3UT Sept 24th, fits my schedule better.. This would decay UARS over North America in a dark sky at a convenient hour on Friday night.. Derek - in the form of a pretzel with all appendages crossed. PS.. "Track the UARS in RealTime" http://www.foxnews.com/scitech/2011/09/21/exclusive-track-nasas-falling-65-t on-satellite-in-real-time/ Which reminds me of a question.. How do I change the displayed sat on Heavens Above?? -----Original Message----- From: seesat-l-bounces+breit_ideas=poyntsource.com@satobs.org [mailto:seesat-l-bounces+breit_ideas=poyntsource.com@satobs.org] On Behalf Of Ted Molczan Sent: Wednesday, September 21, 2011 1:51 PM To: seesat-l@satobs.org Subject: UARS: Satevo decay estimates; ground track plot Propagating USSTRATCOM's orbital elements of UARS (91063B / 21701) with epoch on Sep 21 UTC, using Satevo, indicates decay late on Sep 23, roughly between 18:00 and 22:00 UTC. This is consistent with Harro Zimmer's estimate of 20:05 UTC +/- 5 h, which he posted 24 h ago. I offer the following ground track plot to help visualize where UARS could come down during that period. http://satobs.org/seesat_ref/misc/UARS_decay_2011_Sep_23_UTC_v1.jpg There is still potential for the estimated time of decay to shift somewhat, before it begins to narrow down.
