I observed Columbia during its re-entry this morning from my dome on Kitt Peak in Arizona. It first appeared low in the WSW looking much like an airplane with red running lights visible, slightly flickering. The luminous trail was visible immediately when viewed with binoculars. The Shuttle brightened to about magntiude -2 as it culminated about 5 degrees above the south horizon. It was a briliant pink color then. It finally passed behind the McMath Solar Telescope and then over the horizon. The trail was easily visible to the unaided eye more than 5 minutes after the shuttle passage and was faintly visible still in binoculars about 12 minutes after passage. It was fun to connect to the KSC web page with live views and watch the landing and rollout. Looks like it's home safe and sound. Jim.
