Kevin Fetter, Tim Luton, Greg Roberts, Brad Young, and I, contributed observations used to determine the following element set: OTV-1 401 X 422 km 1 36514U 10015A 10143.39927801 .00002164 00000-0 33855-4 0 08 2 36514 39.9921 169.4496 0015676 209.9290 150.0626 15.52672217 07 Arc 20100520.33-0523.42 WRMS resid 0.036 totl 0.012 xtrk With Brad Young's observation this morning, the recent observational arc has grown just long enough (~3 days) to permit the current rate of decay to be determined with reasonable accuracy. Precision should improve as the arc grows, but the rate of decay appears to be about as expected of a payload, and not debris or a rocket body. The small quantity of optical data obtained so far, reveals a standard visual magnitude of 5 (1000 km, 90 deg phase angle), with a coefficient of phase of 0.014 mag/deg. When we reach 50 to 100 observations, the values should settle down; until then, they are likely to fluctuate somewhat.
