Yesterday evening in a hazy-cloudy full-moon-lit sky, we saw a spectacular Iridium-like flare from Nimbus 7 (11080 = 78-098A). We had watched it pass to the right (West) of Sagitta, noting, in binoculars, that it was as bright as epsilon Sge (V=5.67) when in a very few seconds, at about 1998 Oct 05 23:35.2 UTC, it brightened to about magnitude -1 (i.e. brighter than Vega's +0.03, much fainter then Jupiter's -2.9). Has anyone seen this flaring before? (The only other time we'd seen this objects was 1998 Jan 11/00:01 UTC at an apparent mag of about +5.2 with no hint of flaring.) Quicksat output (edited) for this pass ... 40.107 74.232 69.
