The elsets must be correct.

I observed both objects last evening.  The Landsat 7 R/B passed below the 
Little Dipper (25az, 28el) at 01:23:40 UTC, 17 April at about a 4.5-5.0 mag.  

At 02:57 UTC I observed Landsat 7 at a 6.0 mag in the NNW (20el).

Both objects were on time and on track using the OIG elsets.
