Thanks to Bjorn and Tony for their help! In fact, I did have a current elset but the sat was in early twilight. When I changed the sun elevation limit from -7.5 to -6 degrees, I was able to predict the sat pass correctly. Something similar happened tonight: 03598 ATLAS CENTAUR R/B made a pass in early twilight, and was near mag 2.5 (predicted mag 3.7). I had to tweak the sun elevation limit to capture the whole of the pass. In the future I will try -6 instead of -7.5 degrees.
