Russell Eberst's precise magnitude estimates confirm USA 144's standard
magnitude of 3.4, which was based on a single early observation in June.
Russell's 16 magnitude-points between 23 Aug and 2 Oct UTC were scattered
within +/- 0.5 mag of prediction. On average, the observed points were about
0.056 mag fainter than predicted.
