Hi all, Thanks for the notes about TRMM I'm inclined to believe TRMM was what I observed. The following elset from Stephmon@aol.com and Mike is much closer to what I saw: TRMM 1 25063U 97074A 99081.22196309 .00080089 00000-0 52670-3 0 6919 2 25063 34.9943 33.5964 0001554 240.2261 119.8315 15.74442193 75574 Another mystery solved. So, why is TRMM's orbit adjusted frequently? I lost the web site addresses to all the reference's on Satellites in a hard drive crash. Jim
