Last night around 05:05 7-5-96 (UT) I was observing 95-58B visually and saw another satellite about 5 deg. south of 58B brighten up from invisible to about magnitude 0 for about 10 seconds and then fade back to invisibility. It was moving north at about 1/3 the speed of 58B and both were near the handle of Ursa Major. I'd also estimate the sun was directly below it, so it probably caught a specular reflection from the sun - coord = 40.0876 -104.7932 5025 ft.). If someone can ID it, I'll keep an eye & video camera open to that location the next few nights. Thanks. R. B. Minton
