That's fairly high. They would have been looking out for:

3,000-6,000 miles - Science satellites
600-1,200 miles - Spysats
300-600 miles - Weather satellites, photography satellites
250-50,000 miles - Early-warning satellites, Molniya communication satellites
200-250 miles - International Space Station
115-400 miles - Space Shuttles
100-300 miles - Navigation satellites, hamsats
