I may have inadvertently given out some bum information on optical sightings of the shuttle; following are the correct times for shadow entrance for this evenings' passes: 11/30/83 22:06:27 UTC, 23:35:57 UTC Both occur during passes visible from my QTH (NJ); the first will give almost 5 minutes to sight the shuttle before entering shadow while the second will disappear only about 1.5 minutes after rising.
