I observed USA 193 on a 10 deg elevation pass. The phase angle was high (which means I was looking mostly into its shadow), and the object was at the low end of the expected brightness range, about 2 mag fainter than predicted. 29651 06 057A 2701 G 20080221004025600 17 25 2058586+443405 18 S+070 05 29651 06 057A 2701 G 20080221004032400 17 25 2045221+462022 18 S+070 05 IOD format: http://www.satobs.org/position/IODformat.html Site 2701: 43.68764 N, 79.39243 W, 230 m The object was 2.7 s early relative my 1.25 day old elements (shown below), and within 0.05 deg cross-track.
