The weather cleared here in time to see an excellent pass of Mir and STS-91. STS-91 led by about 40 seconds, passing very near Kochab about 0326 UT 10 June, then disappearing into the earth's shadow near Vega. STS very bright, slightly brighter than Vega. Mir a mag or two dimmer, yellowish. Jim Mason 38d39m48s N, 90d19m51s W, 550 ft.
