Details:
The CSS made an overhead pass tonight, missing the zenith by only 1° while reaching a brightness of magnitude -2.2. The few times I've seen the CSS I'm always struck by how high it can get before it becomes readily visible to the eye--at least 1/3 the way up if not more--and the photo shows that it's not just my imagination or lack of attention: the right (west) side of the track is largely missing. What's not shown is its distinctive red color until it gets close to its highest point, when it turns white and stays that way until it disappears. Tonight it disappeared into the Earth's shadow near October's rising Harvest Moon, shy 2.5 hours from being 100% full.
