Jim,

Thanks for the update.  A good opportunity for a shameless plug for those
who have been sending the ARISSat-1 team telemetry to keep it coming.  You
may well be the one to capture and send the last data!

73s,

Alan

Subject: [amsat-bb] ARRISSat-1 (37772) decay date update for 2011 Dec 14

Greetings,
 
It is time for another decay date prediction update. 
 
As the satellite has gotten lower the atmospheric drag has 
increased significantly. This prediction update uses solar data 
through 2011 Dec. 14. The fit only includes orbital height 
data between Dec. 9 and Dec. 14. 
 
The decay date now indicated is 2011 Dec. 31 with 
a rule-of-thumb error estimate of about +/- 3 days giving a decay 
date ranging between 2011 Dec 28 to 2012 Jan 3.  
 
Jim, N8OQ
